65 Mustang w/front Ridetech coilovers. What rear shocks?

[65coupei6]

I am ready purchase the front HQ coilovers using my OEM upper and lower arms. The distant future might involve a 4link in the rear. But, for now what shocks should I run in the rear? I currently have Edlebrock IAS shocks on all 4 corners.

Mostly street use. Maybe some track use after the 4link.

Thanks.
