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.
