Need a couple of chassis dimensions pls

Bruce I had a measure up of the getrag 265 and a t5 manual 5 speed box and input shaft centerline to the lowest part of the box is around 5" - 61/2". V8 yank flywheels are about 13" to 14" in diameter, bmw is probably somewhere near the same so you dont want the sump to be much lower than around 6" below the crank centerline. It all needs to go as low as poss without tearing lumps out of it over speed humps so reckon on an inch of sump under the car as a max and that will put the lowest part of the box under the car the same as the engine.
