You'll just have to put it together and see what fits and what doesn't. Then you'll have to decide what to modify and what to leave alone. You are trying to cram 10 pounds of stuff into a 5 pound bag.

It really comes down to how hard you are going to drive the car. If you are racing it hard then you'll want to put the best oiling system on the engine even if you need to cut things up. If you are just cruising the car then use what fits.
