    does anyone have pics of a 2wd SM420 in a 67 (or so) model pickup. i am looking to put a 420 in my pickup and have found a tranny out of bus, but the crossmember is tied into the bellhousing, i think this is because the motor mounts on the bus were located differently than on our pickups. It would seem that a lot of weight would be unsupported if the only crossmember is on the bellhousing.

    Thanks
    Marc

    All the SM420 trucks I've had all had a crossmember under the iron bellhousing. I don't believe there ever was a provision for a tail-mounted crosmember.

    465 also werent tail mounted until some time after 73, all trucks even half ton and were iron bell housing with iron three bolt starter nose with rear engine mounts and crossmember under the bellhousing, when you look in parts and GM listings they are called rear engine mounts

    and 420 were never tial mounted ever, they lasted from '47-67, 47 was also the first year of the eaton gm corp 3/4 and 1 ton axles 5200lb and 7200lb
