Hi, Looking at rebuilding a power steering gear box to use as a spare for my '71. Has a slight drip on the front cover, I've broken 4-5 tools trying to get the spring out. Pulled one from a '72 GS 350 parts car I have & cannot verify the part numbers. It is # 5691676 & has a large 76 cast into it. 3.25 turns lock-lock. My GM Parts Book states #7811197 for a '71-'72 GS & # 7809529 for all except GS. Don't know what I have, suspect it was a rebuilt put on the parts car at one time. Anyone able to confirm what it is?
