New to site w/a lot of questions

First, I'm Retired. This IS my first post.
Now that is out of the way, I just picked up a really clean '73 Scamp body (roller) I also grabed another '71 Scamp w/a Very clean body. NO rust on either one. Ya gotta love AZ. The '73 had been a Drag Race car for many, many years and is set up for a BB. Our intent is to make it street legal again, I know, I know, it's going to take some work, that's OK, it's a project car! So given this info, beware, I will have hundreds of questions!!!
Most question are going to be "what body parts will interchange between years, the Dart and the Scamp. I.E.; Hoods, Grills, Bumpers... Interior pieces; Dash, door panels and such.
Oh, yeah, both are two door a HT's.
For exanple, I like the rear bumper of the '71, will it go on the '73? Can the front of the '73 be fit with like the hood/grill of a 71-72 Dart? (Im using the '71 Scamp as a parts car for the '73) The '73 is already set up with a Ford 9" and K-member for a Big Block.

I'm hoping to find a good search function here as I'm sure most everything I'm going to ask has already been asked and answered before!!!

I have several other 'Toyz', and there is not much I haven't done in the past past 50 years on cars!!!!
