NO Longer Available- sold.
I have an original 9 inch rear I bought a year or two ago for $2100. It was rebuilt right before I bought it (have receipt somewhere) and never installed. Its a 3:50 gear and POSI. The casting near where the summer bracket attaches says C5A or C6A (hard to read). The casting on the orange part which I believe is the date code seems to read 1 2 6 (also hard to read). The housing is pitted as its an old original and there is no tag but you can buy repro's I guess if needed. If I can get $2000 back out of it I'll sell it. If interested PM me. It is located in CT near the Springfield Mass border. I prefer pickup- I personally don't plan to crate it and ship it but could maybe drop it off to somewhere local as is. Thanks.
Adjusting price- asking $1900 or best offer
Just listed it on eBay today 2/21 with a starting price of $1500. Got to build up the parts fund!
