A Body Rear End Options?

Hi Rob, I have a pic of an 8 1/4 F-body rear in a 1964 Valiant but it is too large to download on this forum. I have since taken out this rear and replaced with an 8 3/4. The F-body rear is about 4 or 5 inches wider than an A-body 8 1/4 and car had to be jacked way up to accomodate. I imagine custom offset wheels could be ordered up to get tires within fenderwells(if thats what you want) but possible a better route to take is a junkyard A-body 8 1/4. They should be easy to find and very inexpensive. I've had the F-body 8 1/4 I removed from car on ebay three times with a starting price of $50 with no reserve and it hasn't sold as of yet, and it is a Posi unit. Mike
