Thanks Deejay,
I found that part on M Rutters site, that was the only related cross head part, but I discounted it as my car is a 1975 Model and I assume the original fitment from the factory.
Good advice on the clamps.
Ref the Gomog instructions, they seemed less clear to me as the diagram with the jacks and axle stand supports didn't seem to be anywhere on the site?
As I have one crosshead support strut in place, i was looking to buy one and tension it to be the same as the existing one?
