Boy,
I know what your talking about there Jerry. I'm almost at the identical stage with my "body in white" Challenger build. The cage is a big hurdle, and I agree with Jeff, MPR Mike does outstanding work, but when it reality sinks in, still a lot to do. I hope to have mine finish this fall also.
Speaking of Jeff, I had my Challenger stored at his shop while it was waiting to go in for the cage and look what he did to it.
Good luck and look forward to see yours completed!
