Hey man,
Just reading your thread. I am having similar issues. I bought a 81 V20 last year on ebay for $1300 with trailer. Still not in water. One thing after another. On top of that, I think the Hull may have some internal problems since the floors near the bilge area is bowed, but I dont know enough to tell.
Anyways, you said you had $5k to spend. This might cost a little more, but it looks sweet. $5k is the buy it now, bid may be lower. It would probably take you a weekend to get it, 10 hours down, $49 hotel room, and then 10 hours back.
Take a look:
