I have 66 Galaxy that I bought for parts. How can I tell if it is a 9 inch rear? Does it have any specific markings? The car had a 289 in it. It had a cruis-o-matic tranny. I bought it to help with finishing the Stang, I already robbed the radiator,starter, fuel pump, water pump, distributor and coil. All of these parts were fairly new. So I got my hundred dollars out of the car. I am going to part the rest out on Egay. I am just wondering about the rearend. Thanks
