GMONIZ,
I feel lucky. I got quoted $150.00 to $200.00 for labor and I found a master rebuild kit at fatsco transmission for around $220.00. If it needs a ring then I'm in trouble. But there is one lying under where my dad had big bales for his neighbors cattle. I couldn't beleive it. There were two 283 complete motors there too. My dad says they date id back to 1957 chevrolets.
It sounds like I need to do the rebuild though.
