Hey everyone, I'm new here and have a few questions about a three speed transmission I'm rebuilding for a buddy. The transmission is in a 1964 f100 223 SWB but it isn't the original.

Upon tear down I found the cluster gear, reverse idler, sliding gear all have chips in them so I figured we might as well replace all the gears and do a complete overhaul.

So far this is what I have found to be in the transmission:

Cluster gear: C2AZ-7113-A teeth count 27/23/17/14
Counter shaft: C0AR-7111-A
Reverse idler gear shaft B-7140-A
Main shaft: B5C-7061-A
Main shaft bearing: 51A-7065-A
Input shaft bearing: 8A-7025-A
Main drive gear: B6C-7017-B tooth count 16. Ten spline 1-3/8
Intermediate gear: C1AZ-7102-A tooth count 22
Reverse idler gear:??? Tooth count 17
Low reverse sliding gear:??? Tooth count 28
Synchro sleeve:???

I am hoping someone might be able to fill in the blanks and point me in the right direction for NOS parts. Thanks in advance for all the help.
