Yeah, had a closer look last night - they are quite obscure. IF I can get the rest together, it won't be too difficult to turn up a couple of adaptors to convert the thread to a standard brake hose size. - And there's a load of post bore passage plugs that could be used too (hopefully a more sensible thread on them, but not pulled one out yet)
There is a variant takes the "internal" PTT- but it was only made for a year, so a bit like the proverbial rocking horse droppings.....
The Rams I;ve been offered are still attatched to their original clamp / swivel. The easy answer I supect is lying in a pile of dead engines...... Bottom line is if my swivel bracket fits between those clamps, problem solved. (the powered ram fits my swivel bracket)
