I bought my Saginaw at a swap meet for $75 a few years ago and it's still
working fine. I replaced some gaskets and the speedo gear then bought the
$200 shifter from Patrick's.
Mine has 3 grooves and is a 3.50 ratio, I counted the turns. This is a
comfortable 1st gear with 3.08 rear gears.
2.54 - 1 groove
2.85 - 0 groove
3.11 - 2 groove
3.50 - 3 groove
The trans shop had the seals I needed. As far as other parts, I saw 3 of
these transmissions for sale at the last swap meet for $75 (for all three).
They probably weren't in perfect shape but looked like they may have still
had all the inside.
