Does anyone know how to make the mounting plate for the Sanwa JLF-TP-8Y? Are there any tutorials or anything that someone can guide me to or a template for it? Thanks in advance.

You can get the exact measurements on Akiharbara shop website:

Wouldnt be very hard to make from a good solid sheet metal from there.

just mark the holes and drill. I used something like 1/16th aluminum sheet metal and it was plenty strong.
