I got to the front suspension and there are some odd cylinders bolted to the spindle or in that general area there’s a lot of crud so hard to see. I’ve tried googling it and using the search function to no avail. The label says warning high tension road shock damper made in Dayton Ohio part # 5025179 I’ve asked everyone I know what it is and with no result.
They are as you posted "High tension road shock damper...179" Very rare, but not in high demand either (In my opinion only). They were offered in an accessory catalogue back in the day that offered other trinkets that were dealer installed. If you search eBay for that accessory catalogue, you may find one...
Good luck on your restoration! There's plenty of help here on this forum. There's a source for a "plug and play" wiring harness that I would strongly recommend. Look to horsepowerproducts on ebay. Contact Seth directly with questions about it as he has been making them since the 70's. I used it on my restoration and have no regrets. I replaced mine in the 59 because I didn't want 60 year old wiring to make my new truck a road side bonfire so invested the $300 without hesitation.
