Sold Spiral Shocks 1966 Rear 3186919 1969 Front 3192934 Unknown Take Offs from 70 Chevelle

[XXXGoldL34M20]

I recently put Brand new NOS springs on a clients 1970 Chevelle SS 454 with LS5 A/C & M22.

These were taken off the car:
Front are both 3192934 Dated both the same 247 68 (September 5 1968) for a 1969 model.
Rear are both 3186919 Dated both the same 119 66 (April 29 1966) for a 1966 model

Car is pictured with these shocks before removal.

Tried to identify these shocks on eBay and google but no results. Any help much appreciated.

Will sell them "As Is" for $160 USD a pair or $300 USD for all four.
Shipping add $25 a pair or $40 for all four.
IMO the front ones are nice enough to install "AS IS" Rear shocks can use a blast and re spray.
