well unfortunately your not wrong on one but every single one of your points.
For a start to avoid confusion a TE72 is one of the models of T18, its like saying a ke70 is a Corolla
T engine and A engine mounts are very different, even if they wen't the engine position is about 60mm wrong in the forward/aft position. They are also closer together and on a different angle to top it all off. How do I know? well lets just say I have an elaborate jig on hand for a certain conversion. Ke70 crossmembers on the other hand.. well I need to check that one.
There is no "non-rack K-sev", it simply doesn't exist, all KE70s and AE71s have steering racks, all models of T18s including TE72 have steering boxes, so that doesn't work and that's assuming it would even bolt in.
so where are these mod basics from?
