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!
