No. There is a gap in coverage between the 7EC/7FC and the later Citabrias. The Champion Company issued very few publications, but we do have:
B20-602 Parts Manual (7GC/7HC/7GCA/7GCB)
B20-661 Service Letter Collection for same.
For reference purposes, you can use the early Citabria Service Manual B20-551 (which contains supplements covering the oleo strut gear), as the airplane is very similar, including the engine.
