I have a 1968 400 spd convert.All the info from PHS was 100% correct right down to the rear axle stamping.Jim does a great job for all of us. All parts on cars are mostly mechanical,they do wear or break,people replaced them years ago not thinking these cars would be worth more money,with original parts.It was a daily driver for them years back not a collector.Times have changed.Now every thing is a collector to someone.But I'm sure the factory had there problems to,they still do,I know first hand. Every now and then I run into a option code label on new cars that don't have the correct info on them. All in all I have to give Kudos to PHS. Mike
