Let us know how that windage tray/gasket seals on start up. I bought that same thing for my 440 to use with my 6 qt pan and it looked liked those rubber "ribs" were going to line up with the edge of some of those indentations in the pan so I didn't install it. Afraid that I wasn't going to get...
When I restored my 71 Challenger I was able to re-use all of the drip rail moldings and the weather strip moldings. I had the drip rail moldings polished.
My 71 Challenger R/T which I had factory ordered from the dealer has the R/T side body stripe and came with the Challenger script on the fender but no R/T emblem.
