Not sure how much help this is - But i was also wondering/looking for bolts for my car and engine.
Checked out a few bays at various car shows and saw what they were using.
Here's the toyota chart and some pics if it's of any use to you.
I have some average pics of the LHS mount. Looks like two studs on towards the front, and two bolts on the rear - with two dashes and a flange (6T)
