1967 jack hold down sping and hook??????

[Keith G.]

How can a person tell the difference between a repop and the original?

Re: 1967 jack hold down sping and hook??????

here are pics of an original vs repo. the original wraps from the left and the repo from the right. the upkick bends are different also. and then you have coil count and overall length. i did find that the 55-57 chevy repo springs are the closest i could find. the coil count and length are identical.you can find them on ebay. i hope this helps.
take care,
matt

Matt & Keith,

I'm curious to know how much those differences in the spring configuration might translate into deducts. For '66, the jack, wheel wrench and jack retainer (spring and hook) are worth a total of 16 originality points. Although, I've never judged interior, I might divide that up into 8 points for the jack, 4 for the wrench and 4 for the spring/hook. For the spring/hook, I'd further divide the 4 into 2 and 2. If the spring is worth 2 points total, the 20% configuration differences would be work 0.4 pts. Which some judges might round up to 1 point, others might make a dot or check in the margin waiting for another dot to add up to one point. And some judges might never see the difference in coil wind direction or end treatment in the first place.

I'm curious to know how what others think.

Re: 1967 jack hold down sping and hook??????

the hooks for the 55-57 spring are wrong. a person will still need the right hooks for their year. but the 55-57 spring length is correct for mid year cars up to 68. the hooks changed somewhere from single to double. not 100% sure on when. here's an ebay link.

Matt,

Yes, I've seen that auction before. The incorrect hardware on the ends can easily be removed and the correct hook attached. But one is still faced with the difference in spring configuration. But are those spring differences minor enough to escape an originality deduct?

Hello Matt;
Your springs image seems to show the original coil end wrap in the center and the repro. off to one side.
Is this and optical illusion or reality ?
Thanks.

I never looked at the springs that close. Are all original springs right hand wound coils? What does the GM drawing spec call for?

Gary, I am not a seasoned judge, I would say the jack would be 10 pts. , wrench would be 4pts., spring 2 points. My thinking is jack being the most points and wrench being second, and spring being a small part. so the spring does not even warrent a deduct other than a dot next to it noting the problem. and 3 dots= 1 pt.


Matt, if you have a wire wheel the rust on spring will clean right up,Have done this before,as long as the rest the is in tack.

hi ray, both springs wrap up to the center. i think the sharp turn on the repo is the illusion you see.
edward, i had just got the original spring and had not had a chance to clean it up yet. i actually used some wheel acid from my shop and it ate most of the rust off with some scrubbing.
i was lucky to find 2 original springs for a very reasonable price. but if someones choices are limited i think the repo 55-57 spring with the correct hook is the best bet. its got to better than a way wrong spring or no spring at all.

hi ray, i see what you are saying now. it does seem to be more towards one side than the original. but they both do start the kick up from the middle. i think because of the direction of the wrap it pushes the end of the coil more to the outside.

Ed,

Since I've never judged Interior, I trust your points breakdown more than mine. I agree that the jack should be assigned the bulk of the points and 10 out of 16 sounds reasonable to me.

As to the dots, I know some folks use 2 dots = 1 pt, but 3 works as well. With the 2 dots = 1 pt system, some might argue that 1 dot = 0.5, which should be rounded to 1.0, which maybe is why you like 3 dots per point.

I never looked at the springs that close. Are all original springs right hand wound coils? What does the GM drawing spec call for?

Gene,

The drawing for the Jack spring by itself (GM 3737506) is in Adams, p. 105. It says approx. free length is 4.51, diameter is .38 at both ends, and "One coat of black enamel or Japan at source".

The Jack spring "assembly" (GM 3785772) drawing, detailing the "Cadium [sic] or Zinc on Steel" double hook, is in Adams, p. 267.

Gene,

The drawings in Noland books shows right hand wound, but the winding direction is not mentioned as a spec, at least in the drawing Noland shows.

Re: 1967 jack hold down sping and hook??????

The top is a Paragon and the bottom a NOS GM, and both have a wind that the coil assends from left to right looking at the picture, or as stated above winds from left to right. The big diference is in that double hook that closes tighter on the GM than the repo.

hi Dale, do you have the lengths on those? they look like 68 model years.
