The power unit on my 66 rag has lost its enthusiasm for the job and I probably need brakes more than engine at this stage of life. Booster Dewey tells that the K-H unit can be swapped for a Midland Ross that will fit for $214 delivered to me. K-H units are not rebuildable as KH stopped supporting them in the late 60s. What might I expect as the down side to having a Midland unit in place of the KH? Experience?? [Non-text portions of this message have been removed]
