Still working my way through the sprag replacement.
98 Sprint Executive.
cases split sprag out. (51 tooth version)
And as usual with me more questions than answers.........
#1.Will I need to "shave" or alter the case to fit in a new
replacement 51 tooth sprag?
#2. Can I fit a 53 tooth sprag IF I change the starter gear?
And before anyone thinks I am daft read the reason for #2 below.
#3. is the 53 tooth a heavier duty superior piece of kit?
#4. If I use the 53 tooth version do I need to alter the cases?
Thanks in advance.

Awaiting guidance................
