Don:
I don't have a plan yet. Have you been to RT's web site at
http://performanceunlimited.com/cobravalley/? RT has 2 SPF's and sells some after-market parts from this web site. He has a couple low rpm/high output alternators for sale, but they are 1 wire (internal regulator). The 1 wire deal seems okay, but I heard some people say the alternator warning light would not work and others were concerned about 100 or more amps going to the amp gauge and others were concerned with the price and the ability to find a replacement alternator if the 1 wire alternator failed. I need to do more research, but have other things to fix/modify on my car before I fix the low amperage problem.
