In regards to specifically engine conversions, I'm interested in what modifications you have done (or wish you had done) to make future repairs or parts replacement easier?
Personally I can see an issue with the upper suspension arm with most swaps. If it ever needs removing, the whole engine would have to come out to be able to remove the pivot shaft, as the engine / gearbox is in the way on both sides. This could potentially be solved by modifying the subframe to allow the pivot shaft to be removed rearward with some strategically placed access holes in the body.
