I have a 65 D100 /6 3 speed on column 8&3/4. this is a hyd clutch setup. I have BB OE mtr mts for it and it takes a front sump pan and I am going to Iowa in several hours to pickup a granny 4 sp/hyd clutch BB bellhousing complete setup for it. If going with a 727 there is a bolt in OE crossmember available and speedway mtrs has aftermarket crossmembers that slip in to a bolt in end piece on each side for a pretty easy fab. I believe your truck needs a REAR sump BB pan. I have one for you & the pickup I believe is still with it.
