Mop Posted June 2, 2017 Report Share Posted June 2, 2017 Anyone done this? Is it dangerous to run? I've been thinking about doing it and just wanted some opinions. 1 Quote Link to comment
flatcat19 Posted June 2, 2017 Report Share Posted June 2, 2017 How do you plan on doing it? Bolt on spacers? Pass. 1 Quote Link to comment
Mop Posted June 2, 2017 Author Report Share Posted June 2, 2017 I'm not exactly sure how I'm going to go about it. All I know is I've got a set of Trans Am GTA rims and thought it might be cool to throw them on my truck.I've heard from some people that bolt on spacer are sketchy so, yeah Quote Link to comment
willz Posted June 2, 2017 Report Share Posted June 2, 2017 I'd say the best bet is to have your hubs redrilled or find a way to convert yours to an older Toyota 2wd truck, I believe they're pretty close in size 1 Quote Link to comment
datzenmike Posted June 2, 2017 Report Share Posted June 2, 2017 There much more to this. Have you compared the offset? Are they going to stick out past the fender opening? Body will rub a groove in the tread from bumps. Will they be in too far and rub the suspension parts? Are all 5 stud rims the same??? Are Toyota 5 bolt the same as the Trans Am??????? There is probably only one or maybe two ways to get this right and an infinite number of ways to fuck this up. Chev Ford, Toyota, Mazda, Isuzu, Courier and more as well as all the Nissan Hardbody, Xterra, Pathfinder etc. are the same 6 bolt pattern. Find a set you can love that fit. 2 Quote Link to comment
bananahamuck Posted June 3, 2017 Report Share Posted June 3, 2017 Toyota 5 lug is the same as older fords and small dodges so not the same as GM,.. 3 Quote Link to comment
flatcat19 Posted June 3, 2017 Report Share Posted June 3, 2017 To do this properly will take money and time. There are threads about having a Toyota 2wd truck hub machined to fit. Then you need the rear axles drilled to match. With all that effort/expense...you could either buy a Toyota 2wd Hilux or proper wheels you like. Making the truck fit the wheels is always a worse option getting wheels to fit the truck. 2 Quote Link to comment
flatcat19 Posted June 3, 2017 Report Share Posted June 3, 2017 Edit to post above: If, IF, you decide to try the Toyota hub route...the Toyota spacing will still not fit your Pontiac wheels. There are tons of great looking 6 lug wheels to be had out in this world. http://community.ratsun.net/topic/14950-show-off-your-truck-wheels/page-1 1 Quote Link to comment
willz Posted June 3, 2017 Report Share Posted June 3, 2017 Yea as far as getting those wheels to work, I have no idea. I would still think that if the wheels did fit with the correct back spacing and such, having your hubs re-drilled MIGHT be the less painful way to go. 2 Quote Link to comment

But yes depending what offset wheels you run will give final stance. You could convert a Toyota rear end and redrill the front hubs. But now if you don't have disc brakes first go all Toyota or get a disc brake swap kit then you can redrill. Can be done,drilling fronts with drum is easy. Back is easy also if you stay drum but got to pull rear axle's out. 2 Quote Link to comment

Jersey Posted June 4, 2017 Report Share Posted June 4, 2017 Call your local machine shop(s). That is where I had mine redrilled for the Toyota 5X4.5 lug pattern. I had it done 15 years ago at a cost of around $300. I just talked to the same guy who did it for me before and they still do it there. I never had any issues. 2 Quote Link to comment
Rjawm Posted June 5, 2017 Report Share Posted June 5, 2017 Yes I forgot to say all 6 bolt are the same. (well not the Dodge 6 bolt) Or new Fords. And OP, whatever you do, never ever do what you want to your own truck. Always give in to what these "purists" tell you what to do lol Shits and grins, yet another time I post a pic of my D21... Not sure how much of this applies to a 620 unless you change over to D21 front suspension, but machined Toyota front hubs, and a Toyota rear axle is what was used on the D21 in the pic. Not super expensive, medium amount of modification skills needed (welding is needed, and machining of the hubs is required, only for the 5 lug part, not how low the truck sits). I do recommend you grab at least the rear half of the donor Toyota's driveshaft as a hybrid shaft is needed to go from Nissan trans to Toyota 3rd member. Mine is all Nissan except for the last yoke, fortunately the driveshafts are the same diameter and allow for the swap to be fairly easy. There are some threads over on http://InfamousNissan.com that discuss how the front process was done on a 720, the OP of the thread did all the research and fitting, I admittedly only followed his lead. All has worked great so far, at least a couple thousand miles on it. PM mklotz on the forum for more on the machining costs for the hubs. Otherwise, what Jersey said, the redrill, is your best route. I did it on a Mitsubishi truck I had in the late 80's, worked great, still totally safe. I've also used bolt-on adapters as well, the newer true billet adapters made today (as long as you don't go cheap China product) aren't even remotely comparable to the old cast style that still have uniformed peoples panties in knots over their use. I would also add, flatcat is 100% correct on the Pontiac wheels not being the same pattern. They are a 5 x 4.75 pattern, as are most GM cars of that era (a couple exceptions are some of the larger cars and wagons had the 5 x 5 pattern). Doing the swap to 5 lug is really only worth it for a 5 x 4.5 pattern as it opens up access to so many more wheel choices, with a multitude of offsets. For your desire to run those Trans-Am wheels, I'd have to say the adapters are the best option and won't limit you later. But I do believe the offset of them is going to be a huge issue. Lastly, mine is still just yet another opinion posted on the internet, one of an educated and informed asshole, but still just another opinion that holds no more or less weight than any of the others. 1 Quote Link to comment
2wheel-lee Posted June 6, 2017 Report Share Posted June 6, 2017 If you want to redrill to run wheels you have to be cheap, forget it. The cost of properly redrilling hubs and axles is more than a nice set of wheels. My original 620 hubs and axles redrilled to Porsche pattern: Here are a set of Hardbody hubs redrilled to Porsche pattern that I ended up using on my 620: End result: 5 Quote Link to comment
