budsaipan Posted October 10, 2011 Report Share Posted October 10, 2011 Hey guys, I'm installing nissan 720 prothane lower control arm bushings on my 79 620. I noticed that the sleeve they provided me was too small for the torsion bolt to go in. So do you guys know if the lower control arm torsion bolt was the same between the 620 and 720? Does anyone have a 720 one that they can measure the thickness of it so I can compare? Quote Link to comment
motavated Posted October 10, 2011 Report Share Posted October 10, 2011 The same! Fucket bastards.... I know because I got a 720 bolt when I converted my suspension to ball joint. I had to cut and burn my old bushing for the sleeves.... Well for the upper bushings... Quote Link to comment
motavated Posted October 10, 2011 Report Share Posted October 10, 2011 If remember correctly. Same part number... Quote Link to comment
budsaipan Posted October 10, 2011 Author Report Share Posted October 10, 2011 That's what I was thinking. I checked the part number and they were the same. Are you using urethane bushings as well? So now, I either enlarge the bushings itself to fit the original inner sleeve or drill out the supplied sleeve to fit the bolt it.. Damn that sucks. Quote Link to comment
motavated Posted October 10, 2011 Report Share Posted October 10, 2011 pretty much. Or you can just call them and give them the dimensions. Maybe they can supply you with the right shit. What i did notice is that the bottom sleeves can be used for the top! But they have to be cut and only enough for one side.... Quote Link to comment
budsaipan Posted October 15, 2011 Author Report Share Posted October 15, 2011 Alright I just rechecked the part numbers and they are different between 720's and 620's. Might be a smaller bolt. Quote Link to comment

budsaipan Posted October 17, 2011 Author Report Share Posted October 17, 2011 For '79 620, I got 54419-B5000. Quote Link to comment
datzenmike Posted October 17, 2011 Report Share Posted October 17, 2011 Check again. This number 54419-B5000 is for the earlier, up to July '77 (kingpin) Quote Link to comment
budsaipan Posted October 17, 2011 Author Report Share Posted October 17, 2011 Nope. I checked the parts diagram and did search on google. Check this link out: http://www.daiwa-motor.com/SUSPENSION/shaft-1.htm Quote Link to comment
datzenmike Posted October 17, 2011 Report Share Posted October 17, 2011 What can I say bud. Only that from Aug '77 on, ('78 model year) there were a lot of front end changes such as ball joint steering and disc brakes including a change in the lower control arm. These changes were included in the next gen 720 truck until Oct '82 The bushing is 501 just above the highlighted line. . Number 5 and 6 below... Quote Link to comment
budsaipan Posted October 17, 2011 Author Report Share Posted October 17, 2011 Hmm. Thats just interesting. So I wonder why my bolt doesnt fit the metal sleeve. I talked to prothane but he swears I have the right size and he never had anyone calling regarding this problem. If it was the same as a 720, then I wouldn't have any problem with it not fitting. From the link I showed you, my bolt looks exactly the 54419-b5000. So now I wonder if anyone have a 720 bolt and check which style it is from the link. <_< Quote Link to comment
