Need to get the '75 on the road, help me be crafty

[dccarpenter]

I picked up a nice '75 for short money a few months back, I've been working on it at my mom's garage but she's moving so I'm going to lose the garage space for it and will need to street park it in my neighborhood, I need to get it street legal and inspectable in the next few weekends.

I need help with a few issues, any suggestions are welcome,

* Locks: I've got new doors on it(yay rusty ones are gone), but the handles, lock mechanisms, everything is still in the old doors and unfortunately the pieces had broken and rusted out. I live too far from any convenient junkyards to deal with pulling a new set. Is there any kind of legal alternative to the factory locks I can do? If I was in the country I'd just install slide bolts on the doors and lock them that way but know that won't get past inspection here.

* Paint - Was going to ask about what kind of paint I could roll on the thing in winter temps, screw it. Going to just go to Maaco and have them blast it for $199, at least it will be 1 color.

* Rust at tailgate hinges/back of bed - I've got a lot of rust where the tailgate hinges are attached and at the back of the bed..but it is only for a few inches right at the very back. As a temporary fix I wanted to bolt in a piece of 3/16" 3" x 3" angle aluminum to cover the rust , cut the existing hinges off, then attach some kind of new hinge(piano maybe?) to the tailgate and bolt it through the angle aluminum. Any thoughts on this? Any ideas for hinge type I can use?

* The wiring is a bit of a mess, any thoughts on just wiring in toggle switches for the lights? Has anyone done this and not regretted it? I'm also considering just abandoning the existing dash and putting in autometer gauges, just going to replace the ones I can afford.

And here's a reward , of sorts, for reading my long winded post, a pic of the beauty that is my truck
