Ultimate solution would be to use a small Nippon Denso/Kubota self regulated alternator which is very compact - this is what I did on my TR4 engined Plus 4 due to clearance issues with the tubular manifold.
Are you using a new alternator or a recon alternator? Some of the new ones on the market are a bit questionable in terms of quality control so I prefer to have an original rebuilt.
