Well found out some info on my issues:
1. The reason the crank pin hole was too far back and blocked by the timing cover/front main was because I drilled it w/ the oil pump off the car. This allowed the drill fixture to seat on a little farther. Most people drill/pin with the oil pump still in place so the hole ends up for toward the end of the crank.
2. The balancer I bought is an older design. ATI sold it to ThunderRacking back in 6/2007 and the cap head bolts will hit the steering rack. Upated y-body balancers have all flush hardware that is countersunk. So I have to pull the balancer part (Nice thing about the ATI is it's 2 part so I don't have to mess with the crank bolt or front main) and send it to ATI to be updated. Will cost me $40 + shipping but oh well. I could go get regular hex headed bolts but they'd still be really close to the rack and could contact on really hard braking, so I'd rather not take any chances and have to re-redo it all.
