Well...my inbox is empty...try again? I'll PM you a better email address and a phone number, just don't want those out there in public.
The motor is supposedly out of an '84 Rabbit (that ran perfectly, they took this lovely diesel out for a 16v gasser swap :x ), so it should be what you are looking for in terms of bolt size, etc. I also have a ton of old 12mm bolts laying around so you could try one out just to be certain.
It has actually only been sitting a few months since it last ran; you could just slap a head on and maybe some fresh gaskets, or if you wanted to go full bore you could pop out the pistons, give it a quick hone, and slap some new rings in it. Everything is tight right now though, and the bores look fine last I checked.
I kinda liked the idea of having a spare short block laying around...but then again, space is a problem, and I did just rebuild the engine that is already in my car, and it sounds like you are a dieseler in need, so maybe we can work out a deal. Wish I had some pics, sorry, can't take any, but the journey to Seattle ain't that long for you.
