Girvin Inter Damp rear shock
In the early to mid 90's I gave my nephew a Girvin mountain bike with front and rear suspension. It got tucked away in a shed and never ridden. Just got it back.
The rear suspension had a damper with what appears to have been a urethane elastomeric cylinder. It is gone. Would spares be available? If not we can probably 3D print something but would have to guess at how hard to make it.

OK, a few other solutions. BTW I found out the bike is a 1992. Kind of bizarre in that it has a rear suspension but solid front forks.
One could, of course, spend $53 for the replacements referenced above.
I measured the area and it appears the elastomer was 1.5" in diameter with a center hole of 1/2" and 2" high. I ordered a 1.25" OD Shore 40 Urethane tube from McMaster Carr. 6" (enough for three) for $18.50.
Then I found the 2nd best idea of all: wrap the shaft with an old inner tube, zip tied together.
And the winner: cut a bunch of 1.5" diameter discs out of an old tube and stack them together.

Also, a guy on eBay sells a steel spring replacement unit.
