that's an extranal flanged SRW dodge 60 front, the front spring pearchs are 32.5 on center. the extranal hubs are harder to upgrade to internal ( chevy or 91 up dodge ) style. there good fronts but for that price i would look for a chevy. the reasion you would want internal hubs is if you plan on runing locking hubs theres only one style ( the selectro hubs ) that stick out alot. you can get drive falnges for them ( factory 30 and after market 35 spline ), they stick out less and are a hell of alot stronger. i would really look for a chevy for that price. the rear you can pick them up a dime a dozen and it will only be a 30 spline FF axle, 14 bolt or dana 70 would be a better axle to upgrade to, jason.
