Angelo Posted August 12, 2022 Share Posted August 12, 2022 Can someone explain to me what the difference is between the 707a,707b,707c . I have lead on water pump for my 52 L model but it’s out of 707c and I’m not sure if it’s all the same.

Thanks The 707a & 707b are pretty interchangeable across the board, just a few minor differences of which I can’t remember. The 707c sort of has the head turned around so the exhaust manifold is on the other side. I don’t know what other changes there might be associated with that.
