I have 1968 C3 with its 427 and I switched over to a serpentine belt after having issues getting the correct type belt that would last for more than a few months. I have power steering and I went and bought the Steeroids Rack and pinion kit.
The system works well and was a breeze to install. Just be sure to follow the instructions to the last detail or you will spend more time getting it right afterwards.
I had to change over to a newer style power steering pump with a external reservoir. The rack has been a worthwhile swap and I would suggest it to others. The Steeroids kit was complete and was well built. Having a rack and pinion is much nicer than the old style steering these C3's came with. I had to play around to get the right fluid pressure to keep the system from acting strange or making noises.
With the newer electric steering systems coming in I would consider that over a manual rack and pinion with a 1968 Corvette. The prices for an entire kit is cheaper than switching your steering system over.
I will be going to an electric steering boost on my C3 and getting rid of all the hydraulic hoses and fluids.
Has anyone ever tried the electric power steering kit?
Too be honest- I really don't see how that would fit in a C3-
The installation manual doesn't have any pictures mounting that motor inside the car.
I can see a C2- but under the dash of a C3???
I made my own- About $100 all in.
2010 Nissan Cube- from the junkyard- $35 motor/shaft /control box
two u-joints about $70
I mounted it on the firewall-
I also went with a Flaming River manual Rack and Pinion.
New they are $1400- got one off a stalled project for $500
Anyway- I was a lot of fabbing and testing to make/design/cut/weld the steering column-
But the results turned out great!!!
Had to teak the cradle for the Flaming River to get it to fit AND added tubing it the frame so it would not compress the it.
The threads are BOTH RH- so I bought some adapter to change to LH thread- welded them up- now I can correctly adjust the tie rods- the bumpsteer is almost perfect!!!
I also used a bearing for the steering shaft- so there is NO flex in the shaft-
