I used J13 mounts on my J15. E1 through to J15 have the same front plate for bolting the mounts onto. Probably applies for J16-J20 as well but I haven't physically viewed any of them.
The J15 comes with bolt holes in the block, so I'll be converting my 411 to engine mounts that bolt to the middle of the crossmember and block rather than the front cover.
