SA Design Mopar Performance Book

Many of the fixes in the book they engineered themselves and sold
to Mopar performance. BUT they were young and not a lot of money
and Mopar did not pay Venders back then for 120 to 180 days from deliver
and invoice. When they gave up due to lack of funding = I bought some of
the stuff from them and it is somewhere still in my 5000' Shop. Perhaps, I
will find it some day.
