Hollanger makes the interchange manuals , they are anything but cheap
70-74 E body will swap with 71-74 B body for pedals
any long tailshft 833 tranny from 70 -92 will bolt into an E body , I don`t think even Hollander lists that swap , the OD truck 833 need to have the rear shifter pad drilled & the front brg retainer turned down to 4.80 " dia to fit the standard bellhousing or with the small block the V8 OD bel can be used , I have done a # of these swaps , I helped Cuda do his
