Repro sheet metal: Old vs. New?

I have an opportunity to get some AMD sheet metal that is most likely over a decade old, maybe older. ('71 SS-right rear quarter, roof panel, SS hood). In new condition, 2 pieces in the original packaging, although the boxes are raggled up. The metal is all good, no dings, etc.


My question is, is the newer stamped stuff (of any manufacturer) better than the older stuff, either fit wise or any other issues wise?



The guy basically wants today's retail pricing for it, the only real advantage that it is local, so I wouldn't have to pay freight, or take a trip to Carlisle. Then again, if I end up with some kind of issue, there would be no solution that I may get from a reputable vendor.


Or am I overthinking this?


Thanks for your opinions.

Re: Repro sheet metal: Old vs. New?

I think you are right to do your due diligence. While I don’t have a direct answer to your question I do have two thoughts. If it was manufactured by AMD I doubt they would change their tooling, so *should be* the same. That said I think in the earliest days of AMD they did not have all the tooling for Chevelle sheet model and sold another manufacturers parts to have a complete catalog. I would call AMD to see if you can get the answers to those two issues. Good luck!

Re: Repro sheet metal: Old vs. New?

My position is buy new. Someone asking retail for dated repro parts obviously wants to keep them. Your point of fitment without the advantage of return Is important. Make an offer that benefits your overall budget, if it doesn’t, walk away.

Re: Repro sheet metal: Old vs. New?

I would think decade old Sheetmetal might also be subject to incorrect storage. Might be tweaked from sitting or being stacked.
I also think that newer Sheetmetal may benefit from improvements to the dies, better coatings, etc over the years.
Unless the older metal is significantly discounted, I’d buy new.

Re: Repro sheet metal: Old vs. New?

I'd pass on the old Sheetmetal. I often see adverts from suppliers that states "All New Tooling," plus, as I recall, AMD only recently started specing their "own" Sheetmetal... Anything as old as what you're looking at may have been sold by AMD, but AMD didn't spec it.

Since the seller is asking current prices, heck no, I wouldn't buy the stuff.

Re: Repro sheet metal: Old vs. New?

Repro sheetmetal only gets a maximum of 50% of retail, more often less. Return policies do not exist with private sales. Anything I buy from Ground Up I do not like gets a full refund. Quality consistency for repro parts varies. A Camaro tailpanel from AMD that was good 5 years ago was not acceptable last year. Do this everyday and you'll find out. Expect the worst and hope for better.

Re: Repro sheet metal: Old vs. New?

From personal experience, new AMD sheet metal doesn't fit like you'd expect. Yes, they advertise that they have 'new' die's. But the end result is their fenders don't fit. But they look pretty.
And I don't know of another vender that produces, or just sells, quality repop sheet metal. I think if you could research the source of the sheet metal, you'd find they probably all come from one or two factories somewhere over seas.
But maybe my expectations are too high.

Another possible concern is that back in the day they may not have used "weld thru primer"...

Better than original? I doubt it. Good as original? I doubt that too.

I had my car done by a guy, an old school hotrodder, who was a real metalworker. He had an English wheel and was a master working with that wheel and with a welder. A quote from him may tell you something.."I would rather make my own patch panels and weld them in than deal with aftermarket sheet metal".

One of the things that convinced me to hire him was a 68 Chevelle he had done At the time only 69 quarters were available but the 69's had openings for running lights down on the lower rear side of the quarter panel. He made patches to fill those holes making them into 68 quarters. Looking at BOTH the insde of the quarter (trunk side) and the outside of the quarter there was no way to see what he had welded in. I got to see the before and after ...one quarter before patching and the other sdie quarter after it was done. Amazing work. I know the patch itself is not a big deal...more or less a flat piece with a tiny curvature to it but once he fnished welding and grinding it was indeed a masterpiece. I saw other work he had done that required much more extensive use of the wheel and it was just as impressive as those patches on the quarters

Well that depends on the situation, parts available and their quality. I do this everyday, as do many other shops. I've used some repro panels that fit great. I like to repair assembly line parts if possible. NOS and late stamped NOS often need work because the dies are worn. Not unusual to throw thousands at NOS parts to make them fit well. Show quality and the bill is higher. I took on a 57 Chevy stepside that another shop started and they used repro doors which fit very well; nice gaps with no mods. As I said earlier, there are no constants in this industry. Those who don't have to deal with every make and model coming into their shop have it made.

No company uses weld thru primer on new panels. You may be referring to EDP, which gets removed on restorations. Different EDP procedures apply to the collision industry.

Some Dynacorn parts come in weld through primer.

What kind and what parts? Zinc? I've never purchased a full panel in weld thru primer. Interesting.

I’ve had interior floors, trunk floors, trunk extensions, tail panels, and cowl shoulders come that way.
