type of screw in exhaust hanger plate?

[Rdchallenger]

Personally...I do not drill those holes until I install the exhaust....There's just too many variables during assembly....That's just my opinion though... I've got messed up before.

Seeing this just saved me from drilling mine before epoxy and paint as well.

Exactly what I do, especially with Cudas where tip clearance is at a minimum

getting ready to install my exhaust...glad I came across this thread. 

My car was missing the trunk support pieces. I am just going to make them.  Can anyone please tell me what size they are?  I was going to make them 2" x 5.5" based on the depression of the trunk pan but after seeing these photos I think 5.5" would be too long.

The plate is 4.5" x 2.0".   The center of the bolts are each 3/8" in from the short edge.

Bob, that must be the absolute latest production date for any 70 MY Challenger....

Other than than the screw in the corner is what I 've seen, if there's a screw at all...
