New MOPAR fan with a '74 Duster

This is probably the second time I am introducing myself. The first time, was just because I was looking at purchasing a MOPAR vehicle, and I finally took the plunge today.

I took the plunge and purchased a 1974 Plymouth Duster with a 3 speed manual and what it seems to be a 360 (not stock). The car was set up for drag racing but I plan to make it more streetable.

I admit, I don't know much about MOPAR's but I'm learning. I'm more of a Ford guy, but it was time for a change.

The body on this car is almost flawless when it comes to rust or damage. The interior needs some work. Lot's of broken plastic pieces and everything seems to shake and rattle when the engine is running. I'm not too crazy about the interior color.

I bought this car mostly because it's a cool looking muscle car, it's smog exempt since it's pre-75, and because it's got a manual transmission. I really dig manual transmissions.

It's been non-op'd for years, so it's time to get it streetable. I need to address the following issues:

1) Brakes (they don't seem to work well)
2) Seats (it has racing bucket seats that are impractical)
3) Engine idle (idles too high, too loud, exhaust fumes EVERYWHERE)

Hopefully you guys can point me in the right direction for these things. I hope I made the right decision on the right model and year car.

Thanks for any help!
