the early a12 mounts diffrent to later a-12 and 14+15

but the last three mount the same

in other words if you have a 120y motor in it already the a-15 will slide straight in

the only 1200 utes that a-15 will slide straight in anyway (from factory) are 1980+ models cause they had the later a-12 anyway

i also have some plates that allow mounting later motors into early a-12 crossmember so give us a yell if you have any dramas

p.s. later a-12 can be identified by dizzy half way back on motor instead of under number 1 spark plug
