1970 Muncie 3925660 Main Case
 

Have a nice clean 1970 factory dual plug 660 Muncie main case for sale. Stamped code is POK28A,VIN is 2OR134358. My research leads me to believe that it was a M20 in a 1970 Pontiac GTO or Lemans. I just had the case cleaned and inspected at my local transmission shop. It needed two 3/8" helicoils installed in the front bearing retainer threads-now it's in perfect shape. The front and rear countershaft bores are nice and never leaked when I had this case in my Camaro 15 years ago. $325.00 plus shipping. F and F paypal. 413-262-3445,Jim.

Asking $325.00 or b.o.
