Need opinions: What to do with $500?

[jmil1974]

Well, I am stuck. I have $500 from Christmas that I am going to spend on ole Shirley. Question is, what should I do? Here's some options I have been kicking around:

OD tranny, there's a built 200-4r on ebay right now. Would be damn near a bolt in deal, important for my skill level. This would make it cheaper to drive her (MPG) more often.

Checkmate soft cover and exhaust, would be more palatable to look at and for the wifey's ears.

Power windows and locks and sound deadener,nicer to drive

New bed wood and shocks, nicer to drive and look at

Gas tank relo and stereo additions
(have CD, amp, 6x9s - would add sub, eq, and maybe dash speakers) -- just cooler to drive

Piece together a TPI or TBI (more likely) EFI system. more driveable and maybe some MPG

I am feeling a little flaky about priorities as none of it is truly NECESSARY and I just want to do it ALL. Any thoughts, considerations, or new ideas would be appreciated!

Thanks!
