Fastzcars,
Looking good. I have a couple of questionscomments.
Where did you get the fittings to replace the hard lines? I could not find a fitting of that type that was that small? 12mm if I remember correctly. I ended up using the hard lines and rebending them. A real PIA but it works now. (I've got the STI rack in my 72 240)
Secondly, did you do anything to prevent left right movement of the rack? If all you've done is clamp it down with the stock Z parts, I think as you turn the wheel, the rack will slip side to side as the rubber bushings deform. Check it out and see if you agree.
And finally, what did you use for a U joint and steering shaft? I ordered a joint from borgeson and welded it to the stock Z steering shaft. Splines matched sti splines.
Are you going to use the Chevy pump?
Just curious as how other people handeled this. Maybe with several people doing this now, each will contribute some info and make it easier for the next guy.
