Went by the local parts shop to pick up a Major Overhaul Gasket Kit... Began by inventoring the kit, sorting out what I will need, some addition gaskets are included for both wide and narrow deck cases.
I installed the tach shaft oil seal, and began to investigate the possibility of getting the accessory case modified for the rear mount oil pressure hardware. As you can see the case has a casting mark for the rear mount. I have seen a couple of photos from other builders where the engine mount will probably interfere with the side mount location depicted.
