Ok so I got an ACCEL HT full size starter that is new and for a SB chevy. I plan on swapping the nose from the Olds starter to the ACCEL. Trying to search if the Chevy drive is the same. Drive gear has same amount of teeth and spacing looks the same but not sure about the pitch. The Olds gear looks like it has much more pitch on the leading edge of the gear. Chevy drive is 5 roller and would like to use that. Haven't gone too far yet but can the gears be swapped?

 

ive swapped the nose cones in the past from bop to chevy with success...

 

Thanks, the more I look at the Olds starter drive it has some wear and thats prob why the front of the gear looks more angled. Trying to search applications and it appears they are the same.

 

I used to replace a fair number of these starter drives many years ago when I worked at a service station. As far as I can recall, there was only one style for the GM cars. The only possible difference may be that they may have offered a high torque drive in addition to the standard one. But I can't swear to that.
