New, OEM Front Shocks 2015 GMC Sierra

[Beer Belly]

I went with Billstiens on all four corners, Spring Base from old front shocks would not come off to be transferred, had to purchase these new front shocks just for the spring base for the Billstiens (not happy). Now I'm left with new, OEM Shocks, minus spring base, cost $600, willing to sell locally for $400 OBO. Danbury Connecticut area.
