Panz and pan gasketz 101 OR? My 727 iz a '62 with a '65 tail shaft. I got rid of all that crap including the parking brake on the back of the tail Shaft by doing that. Parking brakes were set up with the later model 323 sure grip hub to hub with 2 1/2X11 drumz. Trans waz rebuilt many yearz before the Batwagon took flite and then pickled. I had to drop the pan when putting the beast together because the shifter cable would not adjust. Fixed that an the original pan would not seal after 4 tries. Replaced it with new pan from Mancini Racing and that one would not seal either after 4 more tries and 3 different gaskets! Bought a B&M aluminum deep pan, installed it and didn't like the fact that it hung lower then my center link. Wanna talk about speed bumps guyz? You'd all lay awake nitez wondering when you'd hear that awful crunch and so would I! Had 1 3/4"s machined out of the center of that brand new B&M pan horizontally and then took it to my favorite welder and had him weld the two halves back together inside and outside. Then went back to my machinist and had him stick it on his bridgeport and make dam sure the mating surface was flat with the 727 and tried 3 more times with different gasketz the stop the red hemorrhaging to no avail. Found this outfit in Tennessee, followed their instructions for the install and by gawd, IT DON'T LEAK NO MORE.....And Jer iz ah very happy camper, nite all
