hay dont mean to steal the thred but im putting an l20 in a 120y do any of ya know wat crossember and gearbox cross member i would use lol iv got a whole 200b so i was hoping i can use most of the stuff lol

Is the sump hump at the front or rear? 180b crossmember and L18 all bolts in, but the sump is at the back on a L18.

I would use a 180b crossmember and if your 200b sump doesnt fit in, you'll have to get the sump and pickup from a 180b or 720ute L18 or p510/1600 L16 (not H510/stanza they are frontward so are bluebird).

Or if you can be bothered try the 200b crossmember but I dont think it will bolt in,

Have fun!

yer would i use the a or l series box diff and tailshaft

PIGDOG, did you use the 180B LCA's and steering arms when you put the 180B gear in the 120Y? and what struts di you end up using.

yeah used 180b LCAs balljoints and steering arms, had bluebird struts in there while it was sitting around
but you could use any of the bigger datsun struts....or even get late ute or 120y steering arms and use 120y or coupe struts

i'm going to have to find some 120Y steering arms, as i went to stick the Y struts back so i can move it after swapping the springs back and everything to find they don't go on.... if you have a pair in your collection of emptying your shed send me a PM and i'll send you some cash for them!
