Up for sale is a 68 Muncie with all the correct casing numbers. I don’t know the history of this , my dad had it in his garage. It looks to have been modified internally and the speedometer opening siliconed. So I figure it’s priced low at what the case and shaft are worth. I get a great discount on UPS shipping , so shipping shouldn’t be too bad. Asking $600 plus shipping . PM or text 661-203-6953. Thanks, Dave

 

Main case 3925660
Tailhousing 3857584
Side cover 3384685

 

Looks like it has been converted to a three speed, maybe for a circle track car.
