Greetings all. I have a question for the group. My apologies for crossposting. I've recently purchased a 1970 SS/RS 396 car missing its original L34 engine and TH400 transmission. The car is a Van Nuys model and I can't locate a build sheet. I've completely checked under the front seats as well as the rear seat back and bottoms. I've also dropped the tank with no luck. I'm getting ready to drop the headliner to have a look up there. My question is, are there any other possible locations where a build sheet might be located? I'm working on building a replacement L34 with a date correct one. Another concern that I have is if I can't find any documentation for the car, how much of its value would be lost if I decided to correctly covert it to a 4-speed car. Any advice would be much appreciated. Thanks in advance.
