BOP TH350 on LS1
Hello,
The two bolt holes I have marked with pens are blocked when the plate sits in place. There is no way of mounting the trans to the adaptor plate using these two. It would seem sensible to try and use all mounting points.
My only option seems to be to bevel the holes and weld (or what?) the appropriate bolts in place and use nuts.
Has anyone done this?

One thing that complicates yanking the motor out ten times is that the sump on the Moroso 20140 oil pan is very bulky. The trans and engine does not come in or out together, unless the oil pan is removed. Unbolting the engine from trans - still in the engine bay - with the heavily modified adaptor plate is a bitch.
You can never get too naive while doing an LS swap for the first time. So, there you go: the 100 dollar LS-to-old-trans does not fit the stock th350 converter out of the box. The bolt pattern is off by maybe 5/16".

Thanks for responding. Looks like I am going to do the same thing you did. I'm picking up a motor this weekend. Please update us when it's in and working. Thanks again.

Haven't had any issues with this solution over the past two summers. I even took the trans out from under the car, it actually worked with the long fixed bolts and everything (engine in stock position and hooker swap headers still in place).
