Some generic wiring items questions and other things not warrenting their own posts

Here's a few questions that don't warrent their own posts.

1) Anyone know where I can find a 2" rubber grommet for running wires though? something that I can cut the center out of, I need this because I had to cut a 2" hole in my firewall to fit some wires though for my 2.3T install.

2) Also, thoes factory plastic T shaped clips that are taped to the wiring harness then pressed through sheet metal to keep the wiring harness from flopping round, what are they called and where I can find them?

3) Can I get replacement pins for ford plugs? Right now I have some wires held together with solderless spade connectors which I despise, and I don't want to solder these wires together at this point incase I need to remove this harness. I was thinking of getting some plugs out at the junkyard and soldering them in but would like a more factory look with my wires pinned into the harness instead of just soldered to the old wires.

4) For the pipe that runs from the exhaust manifold to the EGR valve, I don't have that and was thinking of using a high heat rubber one if I can, dunno yet. We have a really awesome hose shop in town that can make anything you can dream of. How must heat would this line need to withstand? Or does someone have one they'd let me have cheap?

5) Someone have a spare oil return line in good condition? Mine is all extended out and I can't seem to get it to fold back up. I might have the fittings removed and placed on a new line by my hose shop, but if someone has one for cheap I'd appreciat it.

Thanks for taking the time to read this and help me avoid 5 different posts.

the info on the plug's is good, I didn't know Ford didn't make them.

I have a tube bender, but I'm not sure if it goes to 1/2", I'll have to check. I thought all the EGR lines I've seen were close to an 1", though.

I actually found a 2" grommet out at the junkyard today, I didn't know Lowe's would carry such things, I'll take a look tomorrow just to see.

The car's a 78 so no emissions are required since it's over 25 years. The reason I wanted the EGR was because I knnow that on my 5.0 the computer adjusts timing depending on whether or not it has the egr open or not. Also on the 5.0's the EGR isn't operational during wide-open throtle, I might be wrong but I'd assume that to be true on the 2.3 T's as well.

That aside, I found a pipe today anyways.
