Engine number CJ into an CU engined westy.

[Geordieskydiver]

I blew my CU 2.0L engine up and I've managed to find a replacement, but its a CJ (earlier) engine.

Can this still be fitted and what do I need to swap over from one to the other? (tinwear, dipstick, alternator etc??)

Its a 1980 Westy T25.

Thanks in advance
