Hi Matt, got your email about this but slack in replying, DONT DO IT,
When it did it aftermarket stuff was very expensive compared to now, but if you must the rods are l16 , few choices of pistons and the crank gets stroked 2mm . Dandy rebores is the place to get the crank done. Keep in mind the pistons dont fit the rods which dont fit the crank so if you cant do some of the machining yourself it will get expensive
Buy reasonably priced aftermarket rods and pistons that fit without modification and then sink your money into the head
