Teminology, steering wheels, and carpet, oh my!

[madmatt54]

I'm trying to place an order for some parts to keep the project rolling, and I need some help first.

1. Terminology: What do you call the little air vents in the kick panels? I need some new ones, but can't seem to figure out what they are called, so I can't search for them.

2. Steering Wheels: What do I need to look for when ordering a new wheel? I'm not looking for stock, too pricey, but I wasn't sure what I needed. Do different wheels mount differently... need adapters...are the universal for the most part or what? I'm really lost and feeling quite stupid here.

3. Carpet: I see two types listed, one for big transmission hump, one for a small hump. How do I know which one I have? Any recommendations on brands on places to buy? Right now I'm leaning towards cheaper is better... maybe from brothers. I know the carpets wont be the best from there, but the truck's not going to be a show queen by any stretch of the imagination.

4. Sending Unit: I have a new fuel cell with a 90 Ohm sending unit. I found a nice set of Autometer gauges I like, but on the fuel gauge it says 240ΩE/33ΩF. I have no idea what on earth that means. Help!

Thanks, and sorry for the dumb questions. Just when I feel like I know everything too.
