I know on my 85 truck I have had to mod each tranz mount to get it even close(india/china mounts)



could be another reason it was modded like mentioned

I would mock it up and see if it all lines up and bolts on...if so run it

I have had bad MM that kicked the tail shaft to one side and would eat tranny mounts

and brackets on the wrong side of the engine block ears/lugs will cause trouble also

my inda tranz mount on there now,I had to cut the slots holes open on one end and the bolt/washer only hits 1/2 of the flange

I have to retorque it every so often or it get to clunking when braking and shifting r-to-d

got tierd of fooling with parts that dont fit and hickabilly it was

I think a better made in the usa mount wold be best..if they even have that any more

good luck with it
