Not much, I was going to go over to a friends house today to swap in the 727 I got for it but then I realized.... The 727 is 5 inches longer and I would of needed a new driveshaft and u-joints. I am just going to wait until I get an 8 3/4 so I don't need to have 2 driveshafts built. And the kickdown linkage I bought is for a 904 so I need to figure that out.
