The chances are that as it is the DOHC model it,ll also have the MT75 gearbox, nothing wrong with that box apart from you lose space in the drivers footwell area due to the box being slightly larger than the Type 9 box, Forum member "Enoch" is using that engine / box, have a look at his build blog, lots of useful info & a few laughs too
As for the steel... get a length each week as funds allow, it doesn,t seem such a large outlay then
cheers
