    I have a 99 tahoe with the 5.7 engine. I have a broken outer starter bolt mounting hole. I was hoping to use a Danchuk 10100 adapter plate to mount a new starter up. Well the adapter plate would work but the crankshaft spacer included would not. Are you aware of any crankshaft spacers available for my engine? Any other suggestions would be appreciated.
