Anyone ... Quick/Variable Ratio Steering Gear on a K5

[CJ5 Convert]

Allright I crushed my steering pump with a jackstand this weekend. The good news is it has been leaking for months. Also I'm looking to put a new steering box in. I want something that has less mush than stock but if it is astronomicaly priced I really don't want to do it.

1st Question:

Is anyone running a quick ratio box on your K5 and could it cause any problems?

2cd Question:

I can't find a replacement box at NAPA or AutoZone all they have are steering rebuild kits.

So these are my options so far(as found in different threads).
1. http://www.powersteering.com/ $149.00 for a remanufactured box- 259 for a 16:1 quick steer
2. http://www.agrperformance.com/ $418.00 for one of there boxes with (total control bearings). I'm sure it is better than the first but is it 2 hundred better. The other seemingly good thing (I guess is you can also get a high flow pump).
3. http://www.steerandgear.com/ I don't know crap about these folks but found it in a thread.
4. http://www.classicheartbeat.com/67-72_chassis_2.htm (Classics stuff looks good and The price is around the same as the other remanufatured).

I'd like to know the pro's and con's of all of this stuff. If anyone is running gear like this I would appreciate any input.

3rd question:

Do I need crossover steering or anything like that for my '69 K5 w/4"lift and 33's. I would like to get it on the road shortly and will be doing mostly road and trail riding (no rock crln).

Last question:

Is it a safety thing to have quicker steering n something that is lifted?
