New guy intro + needs help with TCI leaf kit situation

[2Jhead]

Hi,
First time poster here, have had a -59 lwb fleetside since last summer. It was intended to be a driver from day one with little down time but you know how it goes. In short it has a sbc, a th400, a 10bolt/8.5" rear end, a heidts M2 up front, a standard 69+ GM tilt column, 15" rallyes with "police" caps and a tci leaf kit out back. For better or worse I also did a gas monkey style exhaust inspired of their sweptline, see pic. The truck sits in my cramped garage right now so overview pictures are difficult but I will post some when I (soon?) get it out on the road. Anyway I have a situation going with my tci leaf install. The shock mounts have been installed as per tci instructions and so has the rear end I believe, but the shocks end up too far back, please see attached pics. Am I missing the obvious here? Any comments welcomed
