   In a weight reduction effort, I have replaced the 11 lb. Mazda
   starter with this 7lb. unit, and I am happy to report that it starts the
   engine just fine. The bolt pattern is not the same however, and I needed
   to drill new mounting holes in my PSRU back plate. The starter also
   had to be mounted on the back side of its bolt hole 'ears' instead
   of the
   face for the pinion gear to mesh with the flex plate.

   The cost for this 4lb. Weight loss was $19, and half hour to fit.
   The starter is made by Nippon Denso and is available from
   Surpluscenter.com--- 12 VDC NIPPONDENSO 028000 STARTER Item#
   10-1386. They
   appear to have 47 in stock.

   Paul,

   For those who are interested. I received this reply and pictures
   from Steve
   recently. I did check with the people at Surplus Center and was informed
   that this item has recently been sold out. Darn!!. If anyone has a
   lead to
   this starter I would be interested to know.

   Steve wrote as follows:

   "The body of the starter is about 2.5" diameter. These pictures should
   help. In the second picture, you can see the original mounting holes
   I used
   for the Mazda starter."

   I don't don't think the stock starter is that heavy. I think it is
   around 7 pounds.

   Yes here is an old message on the subject back in 2000. It is the
   alternator
   that is 11 pounds.
