With my bolt holes drilled out in my VW Bug saddle blocks, I can now mark the locations where they will bolt up to the MR2s rear cross-member. I need to be careful how I position the blocks to insure that the main mounting bolt (vertical through cross-member) will be exactly centered.
Was it not possible to use the MR2 rear section that had all the mounting for the engine and rear suspension and tie it to the VW rear? I had an MR2, and this is one great idea. 400 HP, better stock up on some more rear tires.
