8.25 to 8-3/4 or nah!??

Currently riding a open 2.45 geared 8.25 rear end in my 75 scamp /360/727 I would like to put an A-body 8-3/4 under my care but do to being hard to find and or expensive I have been looking at other options. I understand I can move the spring perches of a B body 8-3/4 and with right offsets and spacing for wheels can make that work. I've also heard of some sure grip 8.25 rear ends and heard of putting a locker and/or better gearing in a 8.25 also have heard that a 1997 and earlier Dakota 8.25 sure grip would work but I don't really know much about all I my options some advice would be awesome Also let's know what rear end/hear combo you are running. My car is right now an occasional driver stock to mild motor just like to drive it to work/ school etc nothing major no racing. Thanks again
