250 T5 starter

[mehoff400]

so i hope i dont have to pull the transmission and remove the flywheel. I used a clutch and flywheel from a 85 camaro and it seems this is smaller than my original was. currently when i hit the starter the starter wheel pops out and doesn't contact the flywheel due to I believe it being smaller. i checked the starter for a 85 camaro and it looks like it mounts differently than my 65 c10 starter. i also checked the other compatibly for the flywheel and it is also a 66 C10 look a starter up for a 66 C10 and it is the same part number as a 65 C10. any other suggestion?
