63-5 Oil filler cap

[Loren L.]

Do either the 63-4 or 1965 judging guides call out the vertical striations (?) on the original #3828373 caps? The repops I've seen (2 different sources?) obviously have had those "stretch marks" sanded/ground away before chroming. Or is this another situation where the repop is now being viewed as the original?

Re: 63-5 Oil filler cap

Hey Loren, agree on the 'stretch marks' on sides but have a question on the 'dimple' on some of the caps in the middle of the top. Was that an early 63 item?

Loren, Dan -- in 5th ed. '65 TIM&JG, no mention of striations (nor dimple on top). On my '65 L76 cap, the stretch marks / clamping marks -- vertical lines) appear on both long sides between the four ears. No top dimple.

Re: 63-5 Oil filler cap

My 63 cap has no striations nor dimple while the 64 has some light striations & no dimple. (both original)

I think the "stretch marks" and "striations" are symptomatic of worn tooling. In 1963, the tooling for these caps was new. As time went on, it wore and less-than-perfect parts were made, but still 100% functional. So, why change or refurbish it?

With the number of these caps being manufactured at the time, I'm sure that some tooling wore out completely and was replaced. So, there are probably original caps used on later model C2 (and 1968) that didn't evidence tooling wear. I expect it was just the "luck of the draw".

Current reproductions might be manufactured from new tooling or, possibly, refurbished original tooling.

Later service parts had a different configuration of the hump.

On the real ones, there is a distinct half circle in the center but service and most repo has this area as just a raised hump.

Re: 63-5 Oil filler cap

I have a cap with no tooling marks but, has a flat spot on top of the hump.
Its finish is black phosphate(grayish) Has any one seen this finish on an early 63?

Bill, Your cap appears to be an over the counter service replacement. Configuration is not typical either. I have owned a ton of those over the years.
It appears a certain repro chrome cap I saw recently was patterned after your grayish one as it is not correct.

The verticle lines at the 4 corners is what I look for. The dimple on some of the originals is like Jorjorian said.
Go ahead andTry and get a chrome plater that will not remove the dimple and verticle lines. Seems to be impossible. I just had 7 chrome plated and they are all ruined. This in spite of all kind of notes on the caps.

Re: 63-5 Oil filler cap

My original L75 cap has the verticle lines and no dimple, flat spot or half circle on the hump. Late 65, low mile, 1 owner car.

Here is the 63 (left) and 64 (right) Both have the same smooth round area on top even though the 64 is hard to see (poor photo)

Re: 63-5 Oil filler cap

thanks J.D.: but,I think I should have a painted black one for a Sept '62,L84, build date. I will look in Carlisle for one and I will stop by and say hello

Excellent pictures Alan, the later ones have a very gradual hump as it tapers to the cap's edge.......not the half circle look.

Dan, that "dimple" is when you tried to hit it on with a hammer........SOP on a "Bubba" resto......

OUCH! Must have dropped a magarita on it at an Arizona meet.
