so just wondering

Dakota's are on top of the leaves just like cars, w/5 bolt axles & 15" rims, they still came with 9" drums often. The track drum to drum is 63", the axle flanges are 57.24", and
the spring pads are 43.24" center to center( A-bodies are 43.02").They also have 3" axle tubes, so you need 8.25/8.75 shock plates anyway, definitely not a "bolt in"! All larger
rears will need shorter driveshafts too, the pinions are larger/longer, so you really need to find a doner car or be prepared to find and piece together everything. FMJ cars are 3"
wider,the spring pads are 44.46" center to center. My advice, start diggin' for gold unless you've got a lot of spare time!
