661 Muncie case use in 69 Vette

[Rixls6]

I found a Muncie trans that has a 69 Vette partial VIN, and has a 661 maincase. Did GM use these cases late in the 69 model year because of the longer than usual production run for the Vettes and Camaros?
All the other 69 Muncies I've seen were a 660 case.

Rick, my 69Z is a 10D built car (late in 69) and it has the 661 case as well - its stamped P9R15B

rick, are you looking for a 660 case or just asking if the 661's were in vettes in '69 ? if you are , my dad has alot of 660 cases.

Ed,
Thanks for confirming what I thought.

Jeff,
I was just wondering if the 661 case got used in late production 69's, but now that you mention it I might be able to use a 660 case for another project. I'll PM you.

Thanks guys.

my vette produced in 11/69 with tranny date of P9R03B has a 660 case!

Maybe it depended what they had on hand, so some got 660's and others got 661's late in the production run. http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif
