'93 T/A Distributor
 

The Opti Spark distributor had failed after 70,000 miles on me '93 T/A. My local parts house sells a replacement made by Richporter Technology, which is a new unit complete with cap & rotor, for $212. This is a whole lot cheaper than anything else I have looked at, new or rebuilt (local GM dealer wants $850). Has anyone had any experience with this manufacturer? Any advice on this topic is much appreciated...Thanks for any help.
