disappointed i didnt get any replies, but I'll let you guys know how I did.
The parts I bought ( harmonic balancer and timing cover) were listed for the Toyota, not the Geo
everything fit the Geo fine.
front cover - Dorman part # 635-305 (Rock Auto)
Harmonic Balancer - Dorman part #594182 (Amazon)
a word to the wise. be careful with the plastic front cover- very brittle in the cold!
I was able to pop the balancer off pretty easy with 2 screwdrivers, the bolt holes were rusted out negating the use of a puller
