Suspension, sway bars, wheel&tire upgrades, help!!!

Ok all, so I bought dans 71 408ci scamp.

I am wanting to make it into a fun all around car and handle good. and any info would be great as I am not yet to familliar with a bodies, I have been into cudas.

It currently has. new front stock suspension with polly bushings, ss rear leaf springs relocated to fit 275/60 15" mickeys, kyb shocks all around, home made sub frame connectors that seem well built, stock 318 torsion bars, manual brakes with 11" rear drums and front disks and spindles from a 73 duster mounted on the front side, manual stearing, and no sway bars or mounting tabs.

First on the order list is going to be sway bars probably hellwig tubular 1 1/8 front and 7/8 but I need to know which ones I need due to the spindle and disk swap??? also would any other sway bars be better for the $

second thing that is going to be on my list is some 18" coys wheels and sticky rubber, so what I am needing to know here is if an 8" wheel is as wide as I can go with the spings relocated on the stock wheel tubs and what size tire, what back spacing. And what as far as the front???

then probably going to change the shocks, so bilsteins maybe??

After that I am open to any info and suggestions on the suspension as far as what to do next. I am probably going to stay with stock "style" suspension. thanks ahead, I really appreciate any input.
