LM Headlight cups / square hole cups
Posted by: Lane66m ()
Date: April 15, 2018 04:11PM

What's with headlight cups that have a square hole in the bottom? I thought they all had a round hole.


Also, Is there a difference between inboard and outboard cups?

Can't help you with the stamping difference, but Yes - they are different for low beam and high beam positions.

Guess I need to pull the bezels off my Coupe and find out the differences. I want to save a set from the bunch I have and move the rest out of my possession.

Difference is the mounting tab/slot for the adjuster screws.
I 'think' there are also different indentation positions for the headlight nubs to fit into so that a 'fool' could install two low beams or similar hijinks.

So four different ones, I'd guess...

On late models, both low beam buckets (cups) are the same, and both high beam buckets are the same. Earlies and FCs are all four different, right, left, low, high.

So for your late buckets, noneed to open the headlamp assemblies on a car just pick up a low or high beam and set it in the bucket. If it fits, it fits what you are holding, if not, it is the other.....

You didn't ask,but all LM stainless steel rims are the same. And earlies and FCs are all the same, but not same as lates.

Thank you to all. I can figure out the round hole cups I have. I do have a spare outside bulb I can use to verify these.

The square holes ones must belong to another GM model. I picked up some mongrel parts when I acquired RatVair. And the square hole ones appear to be some more of them.

My 74 Vette had square holes - BUT - also some round holes, since I used Corvair parts to fix it.

Just changed the headlights in my '68 Monza conv and it has the square holes in all cups. Also, the stainless trim is not held by the spring, only the cup.

Does the stainless trim have 3 tabs?

Craig opines: I think all four are different on lates too. The parts book shows four different part numbers and calls out markings of R1,R2.L1,L2 Right High beam, Right low beam, etc.

I took the headlight cups and some Vair headlights cups to Maggie Valley. No one looked at them very long. Just some quick glances. That tells me that these cups and mounts are not long for the bins and China will be getting them soon.

Pay for the shipping and you can have the square hole ones. Probably be a better fit for the LED fixture and less cutting. Just have to trim where 3rd tab is for the spring to connect to the trim ring.

Square hole headlight cups are at their new home. Hope they work out and the LED project works out for us that are interested.
