Stock R&P is 4:10 for manual transmission and 4:30 for automatic...
I have a rear with 4:30's you can have for $50.00
I also can most likely still get the rear that is in the same truck as the front came out of for $100 but you have to let me know quick as the truck is scheduled to be crushed....
Are you looking for IFS width? the rears from IFS trucks are 3" wider, my truck is like this, you just get wheel spacers for the front to match, or use IFS hubs on the front.
I personally like the extra width...
