PB Maxima vintage find

[cas22]

Grabbed this Last week off an awesome local seller.
Never had a PB before, always coveted an Ace, but never seen one in the flesh so the maxima was hard to resist.
Looks in pretty good shape as promised, needs some hubs and the driveshafts/bearings etc need love but nothing too drastic.
Also if anyone has any experience renovating the quick release battery set up id quite like to use that too with some oval cased LiPo's
Would appreciate any advice around parts compatibility please, I've ordered some Yeah Racing alloy boomerang drive hubs as these are direct fit and found some shape ways bits, but with its age some of the components look like they could be substituted for a runner, like the rear hubs and front knuckles for optima?
Quite liking the retro bodyshell too.
Cheers
