Wow, Thank you for all the great suggestions!

"If your truck is the 500kg load capacity version, take the front stabiliser bar and bushes from a Gen 2 - this will stiffen up the front end and improve handling in the twisty stuff."
My truck is the long bed with the 2 piece driveshaft. Will that still improve handling?

"I'd consider swapping seats and matching seat belts and maybe a nice aftermarket steering wheel. Look at older Mitsubishis for a new rear vision mirror (out of a Monty or a Raider...?) so you have the anti-glare tilt function and a slightly bigger mirror area. It's subtle but it's another nice touch."
Actually the previous owner had the genius idea of swapping in one of those horrendous huge split mirrors out of a golf cart, so any automobile rear view mirror would be a huge upgrade. Some people man.
My bucket seats are pretty trashed but they are comfortable. I was tossing around the idea of reupholstering them.

"is your truck a 4 or 5 speed? - the extra gear is a life saver on the highway. "
It's a 5 speed but it seems like there's barely a difference between 4th and 5th. Just because I was curious, I downshifted to 4th at 55ish mph and it only jumped about 500rpm(its a sport so it does have a factory tach). It'll do 55 at 2500rpm in 5th and 3000rpm in 4th. And to be fair, I haven't had the chance to get it up to hwy speeds since I did the weber. I'm betting it feels so much better.

Other than that, I guess I need to do some ebaying as well as finding a junked second gen somewhere. Thanks again!
