Plymouth had clinics not sure what they were named
with Ronnie Sox & others from Chrysler teams teaching
I know as early as 1966
he did clinics at tracks too
IIRC he did one or more at Fremont raceway
I went to one with my step dad Bob (Plymouth & Pontiac guy),
on manual transmissions,
I was really young like 7 y/o, it was in 1966
I don't remember much of it
the above mentioned clinic, by Plymouth
It was at South Bay Chrysler Plymouth (SF Bay Area) IIRC
here was a bulletin from the 68 Hi-Po parts
given to the parts dept.s at dealerships IIRC
