Like this. And actually lists them by sizes, caries various sizes for in hot rod related parts. Easy to find for monster 4x4 stuff. Easy to find without sizes listed, easy to find in one size huge fits all.
Try these guys..... https://www.suspension.com/4-bar.htm They don't sell the outer tube is the only downside I see... I bought some bushings from them for a motorcycle project a few years back, I was impressed with the service.
Well, the outer steel tube seems to the kicker for me. I got a quote today, I had to take 21 feet and I about fell off my chair.
How many feet do you need? I think I have a several 3-4 ft pieces (probably more) . Bigger OD like 1-5/8"? DOM right? I could send you a stick or cut it into shorter pieces to fit in a flate rate mailer. Or try Paul Hortons welder series Pete and Jake may sell as pictured if you give them a call.
Onlinemetals.com and Metalsdepot.com will sell you DOM by foot, or inch. Bushing kits, with rings, are available from enumerate 4x4 suppliers. Post the dimensions you are looking for.
Horton has the tube, bushings, sleeves..... http://www.welderseries.com/blog/online-store/urethane-bushing-outer-sleeve/
