OzyDuster74 chassis connector questions!!

Picked up some wheels cheap of market place as exact size and back set i was after. Street Pro 2 Convo Pro Bead lock, Rear 8.5/15, Front 4.5/17. Its an australian company i dont think they sell them in the USA. Front rubber is an Outlaw tyre and rear a Nangkang Sportnex 2r
I also have a set of mono leafs on order, spring offsets and kaltracs. Will be tight getting the wheels to fit, but by shortening the diff shouldn't be an issue. May have a play with the tub especially around the lip to quarter panel
