I didn't do the original 2j conversion, but as far as I'm aware it utilises the original corona x-member with modified welded in new sections between
Land/Range rover rubber mounts and then jza80 engine mounts to the block, which is the rearward of the two available positions on the block.
The jzx100 mounts as I found sit on the forward position on the block, but as is the beauty of these engines all was interchangeable.
2j
The 2j had a modified pan section as it used the jza80 mid sump, now the 1j has a front sump which had to be notched for the corona front bar...
1j
I'm looking at having a bar done up to clear the pan at some stage also.
