I want to build an adapter that is not available to buy. Looking for advice on mating engine/tranny up with homebuilt adapters. I have seen some well made subaru/GM setups and have heard of a chevy 2.8 samurai setup. I have questions about starter pocket and mainshaft to flywheel alignment. My engine and trans will most likely come from the same manufacturer ( sidekick motor-sj410 trans, both suzuki).Thanks!
