Recurved Distributor

[Bob Jones <JONES_M2@popmail.firn.edu>]

I am looking for someone who rebuilds TR6 distributors and knows how to
set them up with the proper springs and weights for mechanical advance
only.  Hopefully they could make the distributor match my 150 HP cam. 
Both Triumphtune and Racetorations do this but the price has gotten a
little too steep, over $200 plus the high overseas freight.  Any
suggestions?
Bob
