Dave, I think most of us don't even know what that is!

Is this the belt like stuff wound inside a housing that pulls against some kind of friction apparatus? If that's what I think it is, then seems to be in short supply. Restoration Specialties says temporarily not available and Rest Supply is down to just two sizes. Wonder if some of the flat belt material McMaster carries would work or would that look too out of place. They have some synthetic materials as well as leather and a leather composite in various width and thickness.

Thanks HH. Yes indeed, it's the webbing for the friction-type shock absorbers, Watson's in this case. Not for me, I'm inquiring for someone else. Guess I'll just suggest he keep trying Rest. Specialties.
I suppose it must be very strong and doubt leather would hold up, at worst I'd guess it's got to support up to half the weight of the front or rear suspension or up to 1/4 the weight of the car body on bounce and rebound so it's got to have really great tensive properties. Never worked on one of these shocks before so I'm pretty much in ignorance as to the details.

I thought this is worth sharing with the Packard group regarding Shock Straps also called Snubber in some circles. Snubber Strap was typically 1 1/2 inch wide all cotton strap about 5/32 thick. It was manufactured by Uniform Hood Lace in Indiana. They manufactured it since inception (c.1919) and stopped around 2014. They claim their Shuttle Loom broke and was not worth repairing. I think that was just an excuse. Several well established vendors have tried to convince Uniform to do another run (say 2500 yards) to no avail. I have been looking for a substitute from other mills, but none don't make it that thick. The best I have found is an all cotton strap manufactured IAW MIL-W-530 Type III. The Mil spec has a breakage limit of 855 pounds. The original snubber likely had a strength of around 1,000 pounds. Also original snubber was coated with Creosote for 1) protection from rot and 2) as a lubricant around the brass shims inside the snubber drum. One mill, Leedon in Rhode Island makes this but won't sell to the public. I couldn't even get Leedon to make a special run of 2,000 yards. Its a wonder how much would someone have to suggest to motivate a mill for a cotton strap.
Options: A vendor in Conn. sells a cotton strap almost as thick as snubber with no coating for $10 per foot. Another vendor, Andy Wise in Maryland offers Kevlar Strap for $15 per foot. Beachwood Canvas in Island Heights, NJ has about 100 yards of this cotton strap (MIL-W-530) (again no coating) for $8 per yard. Beachwood purchased a bunch for a project that never materialized. It's not a standard item on their website. If someone is looking for a cotton strap at a decent price, perhaps this may work for you. A homemade creosote could be made by mixing roofing tar and kerosene. A note of caution, lighter springs may have to be used when rebuilding your shock unit, but believe todays roads are smoother and don't need as strong of a spring. This will also go to preventing this strap from breaking. Beachwood Canvas 39 Lake Avenue Island heights, NJ 08732 732-929-3168 https://www.beachwoodcanvas.com/ Attach file:  (212.70 KB)
