I did that job on my ‘52 3100 with a ‘59 235. The instructions that come with Dave’s relocation plate are pretty good. There are a few things I can add. First there are two bolts with nuts marked “E” and “F” and I originally installed with the nuts on the inside which created a leak path thru the threads. I disassembled and reversed the bolts so the heads were inside and added silicone under the bolt head to seal. Next is I used silicone instead if gaskets and subsequently it leaked. My fault as I didn’t wait long enough for the silicone to cure prior to tightening. Here is my [POST].

I also drove my harmonic balancer on and heres the [THREAD] on that.
