I love the "F" body ratio. I never thaught it was too fast or twitchy. So a slightly faster ratio may put it over the edge? or maybe not? But it is worth a try because the standard Vette racks could be used in place of the ZR1 rack if the ratio is too fast.

Maybe, but Fiero steering shouldn't be twitchy in the first place. That 3.5 turns lock to lock doesn't qualify as twitchy in my book anyway. I preferred driving the f-body with its 2.2 turns LTL. And no a stock Fiero doesn't need power steering but a lot of us are running tires one, two, three (and more) plus sizes bigger than stock.

It does on a short wheelbase...

I believe the ZR1 rack was a ZR1 only item. Could be the amount of assist inside. I'll try to remember to check some part numbers since I have the ZR1 and later part numbers on CD.

Didn't go to well, looks like GM doesn't sell the entire units and I'm missing the gear application charts. Looks like there may have been an early and late '89 car. Late '89 thru 90 have the same number for the steering gear. 91/92 has another. I have no number for later gears. As far as remanufactured Delco gear kits, again the show 2 different 89 cars. Looks like late 89 thru 96 uses kit 26044839 (Delco number is 369090) I would assume the reman/Delco is most of the unit. Numbers may be superceded by now. Best I could do.

I don't know much about the Vette racks, this is the only one I have seen up close but one strange thing about this rack is that it has the small diameter hydraulic cylinder like the Chevette and 88 Fiero (the black still part of an 88 rack is an unfinished hydraulic cylinder) but I have seen smaller GM cars us the larger Hydraulic cylinders than this Vette rack. So if the other Vette racks use the larger cylinder they will have less effort to steer than this rack. Thus this rack would have more "Road Feel"

Adapters are being made at the machine shop. So I will try to get some pics of what I have so far.
