    I spent the better part of yesterday trying to fit the repop trunk filler panel on my 70, it just wouldn't fit properly no matter what I did, I took a shot on craigslist and some guy had one listed 30 mins away, I jumped on it and picked it up, the son of a bitch fell right into place, I have had the same problem with repop fenders, the moral of the story is fix original metal before resorting to repop stuff, its so worth it

    ALL of my sheet metal is GM. It was so worth it for easy assembly.

    I agree. That doesn't apply only to sheet metal. Very few aftermarket parts for any part of the car will fit and perform like the original GM parts. Never throw away any original part that can be fixed even if it means lots of work. Never modify anything original on the car to make aftermarket parts fit. Cut and modify the aftermarket part instead and likely one day in the future you can toss the aftermarket part in the trash and install an old half -worn out original part in its place when you find one.

    My body is 100% Chinese . Except for the roof. OK I shouldnt say that . The Chinese trunk lid was so bad I threw it across the garage and replaced it with an almost as ill fitting rusted out OEM model from ebay. The rest of the parts give me plenty of stuff to do. Painting in April.

    To be fair Ive turned a '79 into a '70 ish so I'm a heathen to begin with.

    You can make Chinese parts fit. It just takes more fitting and its really the only choice if you have a big block with a decent intake and want/need a cowl hood.

    I'm going through quite the exercise to get proper pulley alignment using all OEM stuff except for a proform alum water pump and summit balancer....

    Mine is all repop. Only original parts being the doors and roof and the trunk lid. Quarters, rear sheetmetal, entire front end etc. The reproduction stuff takes a little more work but its not filled with bondo from 50 years. Any body man worth his salt can make the parts fit. Its not like original quarter panels don't take the same amount of work to install that reproduction panels do. If you are going for a concourse rebuild reproduction parts wont cut it. The holes are all over the place and it becomes a making it fit exercise despite the issues but for normal use they are just fine.

    Only part I had an issue with was the trunk lid . Couldnt get that thing lined up to save my life. Trashed it and found a good original.

    I have repo parts that fit great and parts that don't. It can be annoying. Even interior parts are a hit or miss.

    Interior parts are worse. With exterior sheetmetal if it doesnt fit you can just weld it up or do other "tricks" to get the gaps right. What are you going to do for poorly molded dash parts?
