I have a crossmember i fabricated for a ca18det conversion in a 1200, It mounts the engine as far back and low as I could get it, about an inch space from firewall and notched for lower sump, I used 5mm mild plate and tig welded it. It is of no use to me now as I have gone back to a series for the time being, but I need a crossmember to modify in my spare 1200 for a L-series conversion I am planning later in the year, So wishing to trade.
EDIT - It also comes with a set of new R31 rb30 engine mounts I used with the setup.
Here are some pics of the crossmember just after fabrication, its the same now but the pics are old.


And here are some pics of how the engine sat in the bay.



I live in brisbane and would prefer to swap with someone up here as swapping is easier, Otherwise with post as I have been ripped off a few times on forums, even once on here.
If you would like me to post it I would prefer that I received the other crossmember before I posted this, If you don't agree with those terms I won't sell to you, It's for my protection (which is why I'd rather swap it).
$150 + your crossmember.
Cheers Alex.
