Long Travel Shock Selection for Ford Shock mounts

[KK5 Native]

I've ordered a pair of the Ford shock mounts to go on my 80' K5 D60.

Any suggestions on which shock I should run? Do the different brands of 14" long travel shocks vary enough in eye to eye length to matter? Not sure if I should spend the money for Bilsteins/Rancho 9000's or just go with a cheap procomp.

Part#'s would help.
