hello' I search the forums and I could not find an answer so here's my question I am looking at putting a mega shifter from B&M part number 80690 on my 1968 Buick LeSabre I was wondering if anyone can confirm the fitment of the shifter on the st. 400 transmission as I know the th400 is similar B&M says if the transmission pan is the same as the th400 that the shifter should work thank you in advance, Gregory
