I am rebuilding the suspension seat on my ZAE. Suggestions for the shock?

A shock used for a golf cart works well if the studs are cut and threaded proper length. Google Club Car shock 5022

There is a golf cart shock that works with very minimal modification, don't have the info handy, maybe someone here will.I think I have an extra but cant get to my barn right now, email is open

I just take mine to the auto parts store and match one up for the length

Taking parts to parts stores now a days is a challenge in itself. If you can’t tell them how many doors is on it, the person just looks at you with a blank stare. One time I needed 8inches of 2” hose, knowing I may have to buy a preformed hose and cut a section out. The guy behind the parts counter asked me “what does it fit”, I answered that he wouldn’t have it on his computer. Again he asked the same question to which I replied “a 1931 Case L”. He had a blank look but started pounding the key board. After a while gave up and suggested that I goes elsewhere. Never did take a tape measure and go look. The NAPA store I use now is really good about it.

That's for sure, you gotta go to a good parts store. Otherwise most of the time the first thing they say is "year, make and model"
