Hot Rods Fixing blc 682J headlights ??

I picked up a used set of of blc 682 J headlights . I was curious if anyone knows best way to fix this. The bolts that go through the headlight mounts and that move for adjustment of headlight are two different lengths , you can see it in the picture .

Obviously they need to be the same length but didn’t come that way when I got them. Other than the non matched bolts, the rings and headlights themselves are in very good shape, no rust or huge dents .

Best way to remove the piece that is riveted on there ? Once off can I re use it with the matching correct size bolt?

Or do I have to buy a replacement part like this???

This is a DIY job

 

Which one is the length you want?34Phil has one answer , it looks like the rivets on the long one have been changed. If you need long open the light and grind the rivets off ,

 

I need the longer so I will grind those rivets off,thanks !

 

Took rivets out of mine and replaced with polished brass round head screws. Flat blade
Looked great to me....

 

I have done this many times. Grind off the rivets from the inside, use a punch to knock them out. Be sure to save the rivets. Change the bolt to what you need. Re-assemble with the original rivets, and weld them in place from the inside.

 

Weld on a longer bolt?

 

Check out McMaster-Carr or Fastenal for solid steel rivets. Average price each is 20 cents. They have them in all diameters and lengths. IMO, in this case, a much better repair than welding.

 

Grind off from inside.....then bolt them back on. I use new stainless hardware.

 

Too easy.

 

Go to OTB Gear's website. They have all the small parts to rebuild you old BLC head lights. Including a mounting kit. http://www.otbgear.com/Mounting-Parts-C35.aspx
At 24 bucks for the kit, its worth buying instead of spending hours fabbing up a repair.
