Roland A A14 into a 1200 coupe is a very straight forward conversion. From memory only the engine mounts had to be changed plus some wiring as alternator is on other side of engine.
For the left hand side engine mount I welded two together as the engine mount sits about 40mm further back I welded a 40x80mm plate on right hand side with slot for it to bolt up.
As for the gearbox Im not sure with the 5 speed but the A14 4 speed bolts straight up without mods just had to enlarge tunnel a bit with a FBH (
F@$#@$ Big Hammer :)Even better if the
engine and box is for free well worth a couple of hours work changing mounts.
