That's a really cool looking buggy you've got there Tim.. If you cant find the information your looking for, just send your parts to MetalMan and in about two weeks you'll have your motor mount. He made me one and it turned out fabulous.
FYI
My 808 is loving life on its new 1512 2D.s on 4 & 5s. for what it worth..
Question for you, do you what weight oil you'll be using for your center diffs??. Just taking a pole..
Thanks for your time Tim and I'm looking forward to your conversion..
Peace..
