Manual to Auto trans swap and WTB T/C mounts

[nick70]

I am in the process of swapping out the original manual trans in my ’71 K10 to a TH350. I bought a married TH350/NP205 that I want to directly replace. I was told the Trans/T-case were tight and that it came out of a ’72 Blazer. It was only $250 so I couldn’t pass up the offer. I am going to have both units gone through before the swap, just to be safe.

What all do I have to do/buy to make this a clean job?

Where can I buy new T-case mounts?

Thanks in advance for the info.
