Eomund Posted May 5, 2016 Report Share Posted May 5, 2016 So I was working on my headlight swap to halogen. While pulling everything apart, I found one of my retaining rings is badly broken. I can't seem to find the bloody thing. Any parts available that match ours? If not, what's the,usual solution to replace these? 1 Quote Link to comment

datzenmike Posted May 5, 2016 Report Share Posted May 5, 2016 If looking for parts it's done here... http://community.ratsun.net/classifieds/category/7-electrical/?sort_key=date_added&sort_order=desc .My info shows that there are separate inner and outer rings so best if you specify hi or lo beam. 1 Quote Link to comment
Eomund Posted May 5, 2016 Author Report Share Posted May 5, 2016 both are actually the same. It was the low beam that was broken, and I swapped it with the high beam, just in case it,rattles the light dead, I'd rather it be the high. This was more an information gathering thread than a 'wtb'. Seeing if the bezzel is the same as like a 65 Nova or something. Quote Link to comment
Eomund Posted May 5, 2016 Author Report Share Posted May 5, 2016 And per the ebay link, it appears to be the same as the 510. That's the kind of info I was looking for. Quote Link to comment
datzenmike Posted May 5, 2016 Report Share Posted May 5, 2016 They may very well swap but the numbers are 26023-14000 outer and 26025-14000 for the inner. They are not the same as the 510, they may be similar and they may fit. Quote Link to comment
Eomund Posted May 5, 2016 Author Report Share Posted May 5, 2016 As far as the 'inner' and 'outer', per carpartsmanual.com, on the late model 521, they're the same part number. http://www.carpartsmanual.com/datsun/pickup-1965-1972/electrical-common/front-parking-turn-signal-lamps/dual-(from-may-68) It's on the fiche as part #9. Same for both. I did notice the 510 has a different part number, but they do use the same headlight, and per the ebay photo, they look identical. For $20 for 4, I'll give it a shot. I'll post up whether they're the same or not. Quote Link to comment
datsunaholic Posted May 5, 2016 Report Share Posted May 5, 2016 The difference is either the depth or the orientation of the retaining prongs. I know the ones off my '78 510 and '68 520 are not the same. Quote Link to comment

These are Nissan part numbers not some 'on line parts manual'. (and also incorrect) If Nissan has two different numbers then they are two different parts in some way. I didn't say they wouldn't fit, only that they are not the same. Just because parts will interchange does not make them the 'same,' only interchangeable. All PL510, 521, 620, 610, 710 headlamps are 5.75" so it's reasonable to assume some retaining rings will work on other vehicles. Quote Link to comment
Eomund Posted May 6, 2016 Author Report Share Posted May 6, 2016 Just looked it up. The part numbers your giving are for 66-68 http://www.carpartsmanual.com/datsun/pickup-1965-1972/electrical-common/front-parking-turn-signal-lamps/dual-(to-apr-68)the ones I'm referencing are 68-72. I have a 72. The site gives the Nissan part numbers along with the original microphiche images. And hey, if the 510 retainers don't work, maybe I can sell them on. Quote Link to comment
kelowg Posted May 6, 2016 Report Share Posted May 6, 2016 Broken? How? Spot weld separate? Sheet metal shops have spot welders. Quote Link to comment
G-Duax Posted May 6, 2016 Report Share Posted May 6, 2016 I tig welded my tabs back on. Really low amp setting. Quote Link to comment
Eomund Posted May 6, 2016 Author Report Share Posted May 6, 2016 Nah. Truck had a front end impact at some Point in its life. If I had my guess, it prolly got a bit mangled, and instead of fixing it right, the cut a big o'l section out of it. So fixing this one would require some fab work. Quote Link to comment
datzenmike Posted May 6, 2016 Report Share Posted May 6, 2016 I'll check but thought they were for the 521. Weren't the '66-'68 single lamp? Quote Link to comment
Eomund Posted May 7, 2016 Author Report Share Posted May 7, 2016 I'll check but thought they were for the 521. Weren't the '66-'68 single lamp? I don't think so.If I'm not mistaken, they moved to dual headlights on the 520 in the 66 model. Might need to fact check that. In fact, there's a 520 w/ dual headlamps here in town rotting that the old bastard owner won't sell. (Been sitting for 17 years, guy's a horder). I have ordered the 510 retainers. I'll let you guys know if they work or not. And if not, I'll prolly be selling them :p Quote Link to comment
datzenmike Posted May 7, 2016 Report Share Posted May 7, 2016 Correct. October '66 went to dual 5.75" lamps. Aha, found them (on a second page) my mistake. May '68 and on were #26023-78502 for all four. The 510 were a different number but they also are all four the same. However it looks like from the diagram that the three mounting screws are equally spaced at 120 degrees apart. The 520/521 are not. I hope I'm wrong again and these fit. :lol: Quote Link to comment
Eomund Posted May 7, 2016 Author Report Share Posted May 7, 2016 I noticed this too. The ebay pictures, however weren't. We'll see... One item of note. Finished getting the halogen installed, what a difference. Seriously worth it. Quote Link to comment
datzenmike Posted May 8, 2016 Report Share Posted May 8, 2016 I had a 521 in the mid 70s and a local auto supply had a couple of halogen 5.75" lamps that they discounted because they didn't sell. Wow halogen vs. tungston? Night and day. Now it's halogen vs. xenon or HID. Quote Link to comment

Eomund Posted May 20, 2016 Author Report Share Posted May 20, 2016 I have an update on the headlight ring debacle. I can say the rings I received are indeed different than the original headlight rings. BUT, they still worked perfectly. The original (broken) ring The new ring The rings on top showing they line up. I didn't get a picture of it installed, (maybe later). But the holes line up perfectly. Now Ima keep the other 3 for spares :) 1 Quote Link to comment
