Hey Jremig, Ive been following this post and thought I'd add my 2 cents. I watched that drivetrain video and found it very entertaining. Looks just like what you intend to do utilizing your straight 6 and an auto trans. I have a 327/700R4 in my 50 3100 and was on the same page as Pre '68 Dave w regard to cutting out that riveted crossmember that the bell housing was bolted to: hated to compromise the integrity of the ladder frame. So my answer was to cut out just the middle 15" of that crossmember and use a spanner tie plate made of 1/8" flanged plate steel bolted into those eight mystery holes that were on either side of the section I cut out. You'll see by my pics that my tie plate is bolted into eight 3/8" coupler nuts which doubled as spacers to clear the trans pan. In the pic showing the driver side remnant of that crossmember I installed the pivot for my trans linkage.
Cross Member Modification Also I did not have to cut out my floor or firewall. However you do it there is a lot of jackology involved. Think it thru carefully. Good luck. Dave
