Hard Question about Automatic Transmission Mounts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

hubcapboy · 01-10-2008, 06:56 PM

I have a '68 C10 with a 396/TH400... and I'm trying to replace my tranny mount. I've ordered and recieved part number 34-0364 from LMCtruck, but the center to center dimension where the mount bolts to the tailhousing is too small! There are only two part numbers listed on lmc for the year range, one for the th350 and the other for the th400.

I don't mind re-drilling the crossmember for a bad fit, but slotting the plate that bolts to tailhousing is pretty sketchy.

Anyone have any information on there being multiple bolt centers? I can get some pictures if I need to...

Thanks everybody!
