How did I do

I'll check out Kilmat on Amazon. Thanks for the advice everyone. I was just reading a recent forum post here asking the likelihood to recover a missing fender tag and it peaked my interest. Toolmanmike stated that there have been lots of engines, transmissions, fender tags, build sheets getting reunited with the original cars by using the lost and found forum. I'm thinking now what if the original engine and trans for this 71 RR can be tracked down. The guy at the yard that I dealt with told me that a younger guy came and dropped the car off because his father or grandfather had passed. I'm gonna contact the yard to see if they got the info of the guy that dropped it off and see if I can talk to him and find out what happened with the engine/trans. I'd also like to post any info needed (that I have) in the lost and found forum after figuring out about it. What info is usually needed to be presented? I have the vin and title and idk about anything else. Haven't looked for a fender tag or any other tags that I'm not familiar with. Thanks guys
Pull the back seat if its still there and look for a broadcast sheet. It may also be attached to the back of the glove box liner or under the front seats if they are sill in the car.

This is the "Holy Grail" of info on your car and the fender tags can be reproduced if you have it.
