Hi there….yes the 1500 does go in but it’s about 1″ longer than the 1200. So you have to modify the front crossmember to miss the bolts on the front of the block…not too difficult. You fit the Devon front and rear backplates, and use the Devon flywheel, clutch Assy and starter motor. I can supply photos if you like. You need a welder.. Or a mate with one. I live in the Midlands… You can come and have a look if you want, or let me have your email. Regard Martin.
Mark, is yours a column or floor change, because they are different. The column change has a boss on the top for the lever location, the other dose’nt.Apart from that I think they are identical.The boss can be removed with a bit of effort.I’ve got one you can have,condition Unknown, so will need looking at. I’m also going to the barn day so I can pick one up for you if mines not what your looking for. I’m in Sutton Coldfield B76 2SS or 07976764577. Martin.
