I was looking through my .091" (48P) pinions, and came across these... they appear to be EDM cut, and look like ARP/GT1 pinions... they are solder on, and a very nice fit .
 
I think??... I got these from PCH a few years back, but they currently have nothing even close.
 
Any ideas??
 
Stay safe,

Is that a 26D or 36D motor? Are you really sure that's a .091" bore? ARP never made 36D size pinions.

Hi Paul, It is a 36D, done by Mr. Havlicek.........the pinion is 48P with a .091 bore........I have measured more than once  :)

It is not 64P, as stated in my first post...it is a 9T 48P .091 bore pinion.............manufacturer unknown.

OK thanks for double checking. In that case I am stumped. No doubt they are nice pinions  :)
