Distributors can 'work' long past their useful life! Replacing points and condensor is NOT rebuilding a distributor. If you want to get the most from the performance of your engine a very good distributor is a must! Our rebuilt units have had both the vacuum and mechanical advance systems checked and recalibrated. The shaft and internal bushing have been re-newed! These are like new distributors at a fraction of the cost of new. The advance curve of these units is ideal for high performance 1098cc and all 1275cc engines.
