Best gears for a /6 ??

someone has already put an 8 1/4 in the car but I had in mind to go back to a 7.25 because I wanted to stay SBP.

I'm sorry, but now I'm confused Rainy...............
1) If it is already an 8.25, why would You consider changing anything except the gears?
2) No, Dakota rears are way too wide & the spring seats would need cut & moved.
3) Are any of Your 7.25 rears Sure Grip? If so, they can handle what You're planning on.
4) If You have a SG 7.25 I'd purchase it & You can fund your gears, :thumbsup: ! My '64 GT's an auto, so I'm staying 7.25 SG.
5) There's really no shortage of affordable 8.25's from A-bodies out there if Yours is missing???
6) The cost to switch to front discs will be worth it if You would consider the savings not paying to convert the 8.25 to SBP.
