Is there any way that i can get the build sheet for a 1970 Challenger? I looked all the places the internet say it should be. Like under floor mat and under back seat. Thanks for any help.

 

The only way to get a Broadcast sheet is to find it in your car or someone else found yours in their car. In an E body they are usually in the springs of the top portion of the front seat. Found by taking off the plastic seat back. But they are known to be other places including on top of the glove box cardboard insert. You would have to put your hand under the dash assembly and reach up over the glove box insert to feel for one.

Try searching the web boards and Facebook for Broadcast Sheets lost and Found if you can't find one in your car. Moparts.com has a nice section for lost sheets as well as FACEBOOK
