O.K. I know it has been done to death, but can someone give me a quick list of bolt in steering boxes for my poor 70 Lark? I was hoping for a little quicker ratio but don't need to replace anything else. Gearbox has got a major leak in it.
Just got mine. What you are looking for is called a "Z" box. There is a Z stamped right into the middle of the housing. They came on mid-80's SS Monte Carlos, Olds 442's, and Grand Nationals. They also came on mid-90's Grand Cherokees. You will need a rag joint from a mid-80's Chevy truck (can be bought new through GM Parts Direct on-line) and two adapters for the lines if you're keeping your stock power steering pump/resevoir. You may also want to get the spring assembly from the pump. It is behind the pressure line in the pump/resevoir. There are about 4 or 5 pieces in there. I went on TurboBuick board and got a real quick response as that is the place for those cars. There is a place called G-Body parts. I think he's in CT. He has a bunch of them and it was $70, shipped to my door. Here is their website: http://www.gbodyparts.com/index.htm Here is also a good reference website with instructions. http://www.442.com/oldsfaq/ofstr.htm Good luck. Phil
I think this explains it pretty well. There are very few power steering boxes for RWD GM passenger cars produced between 1964 and today. Five, I think. Manual steering in two ratios (quick ratio went obsolete in 1974) and power steering in three ratios. Yes, there are changes in connectors, fittings and hoses, but the bolt pattern and shaft relationships are the same. You can put the new Camaro box in any GM A, F or G body from 1964 to the present. This covers about 50,000,000 cars. You might/will need to swap over the pitman arm and probably the steering gear end plate (this determines the steering stops).
Just completed '96 Grand Cherokee box into a '64 Skylark. Works great!!! The only problem I had initially was trying to find the correct rag joint. I took an alternative route to this problem. Since I also wanted to upgrade my column to a tilt wheel I also used the Grand Cherokee intermediate collapsable shaft and changed the trunion joint bucket at the top with a GM 1" splined bucket. Mine came from the '77 Trans Am I got my spindles from. It's about a 10 minute job to change this. The steering column is the rest of the story since the '64 to'67 columns are long, one piece units. A 30" column from '68 up works well but the '69 and newer ones have the ignition switch/key built in. That leaves you to find a '68 column if you don't want to mess with the electrical. I solved this problem with a custom column. It cost me $300 but it has late model signal switch (common, servicable) with four way flashers as a bonus. I'm happy. Next step is the Firebird spindles, brakes, etc. I have the Hotchkiss control arms and everything but the cars going into storage for the winter. Will do it next year. Good Luck.
