Magnum 5.2 & Doug's D453 Header Fitment Issues

swapping k members isn't in the cards. seems like that'd be way more work, effort and expense. i'll work on adjusting/shimming/trimming things as i can.

i'll trim back the outer "shell" on the steering column. and while i'm in there, i'll snap a pics showing that the starter motor definitely isn't going in. i'll dig up the starter part number too.

so what's this collar do?

i don't know why it had a 3/4" long set screw in it. guess i can just put a short one in right?
