A few road worthy questions

Hi team, its been a while since i've thrown a thread up and its nearly time to get the red girl registered. Some questions might be no brainers and some might be a little ambiguous but any help would be great.

The shorty is not lifted and i wanna run 33s (soon to get a 3inch lift so should be fine after that) but wasn't sure if clearance would be a great issue, remembering that its only to pass a roadworthy thus far, i know they will scrub if taken offroad. The plan is 15x33x12.5 Maxxis Buckshots.

How tollerable are roadworthies with rust, mine has only a little bit, which in saying that is mainly surface and only in patches the size of a 50c coin

The list of things to do at this stage are:
Rear wheel bearings
Rear brakes including slave cylinders
Left hand indicator won't blink (works too well)
New front windscreen
Wheels and Tyres (which I have the wheels)
New rear muffler
Change oils

It currently doesn't have the genuine rear glass window as I can't get hold of one to suit the steel style canopy (if anyone knows of one please message me). I don't see how this could be a problem as I have made a polycarbonate one which uses the gas strutts and the genuine locking system.

These are the wheels



I'll give them one more polish, you can see the difference a sand and paint make.

This is what the old girl looks like now. As you can see the manufactured rear window. Not really like the fiberglass models.
