With the AU 65mm TB are they a bolt on to the EL2XR8 ? I read something about an e-series TPS. possibly sounding as tho it was something extra. ?

The AU 65mm throttle bodies are bolt on to any e-series. You do need to widen the hole centres in your existing TPS a little as the bolt holes in the AU throttle body are spaced apart a fraction further.

Correct. An important point to note is that when the AU TB is bolted up, you need to check the voltage coming from the TPS. It needs to be between .9 and .95 toi ensure consistent idle and shift qualities for the auto. Just modding the holes will alow it to bolt up fairly easily, but the voltage will be wrong. The holes need to be elongated. Do one side, get the correct voltage, bolt ot down, then do the other side
