TH400 Mount Part Number?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I want to change the transmission mount on my turbo 400 but the ones that I am seeing at local parts stores are incorrect. The bolt holes that sit up against the crossmember on the new mounts are 1.5" spacing on center which matches my original. However, the bolt holes that sit up against the transmission on the new mounts are 3.75" spacing on center which is too small. I believe the bolt holes on the top of my original mount are spaced somewhere around 4.5" on center. Anyone have a part number for a mount that has worked on your turbo 400?
