Hello Jerry I have take a look on other saler but the price is more or less the same for the oil pump This is the picture of the piston with the spacer Now, we must mount everything on the engine and check the clearance with the valves and the head because the piston exceed 1,5 mm to the upper block line ( the connecting rod are not very more shorter than the original one) If there is a problem we can remove a little material on the top of the piston, if there is enough clearance with the valves, it will be great for the compression ratio. The last and big modification is, adapt an 5 speeds gearbox from an m35 truck. I have found the gearbox in germany ( very cheaper 300 €) I will send somes pictures of the modification
