I've seen about 10-12 4age engines from AE86 and only one was with 42mm C.J. It was from the last year, 1987. You should recognise if you have 3 or 7 rib engines, and if you have 7rib you have a chance (but not 100%)

you can use a 42mm crank, providing you match it with the correct Rods and Pistons...

Early (most) AE86 came with 40mm, later AE92 came with the 42mm crank, and on to the later 4age AE101/11 Levins...

google for 4age 7-rib block and the pictures will tell you the difference.
7-rib has 4 additional reinforcement ribs on the side of the block--> stronger, later engine
