dynamic63

someone told me that the 64 cars that had the slimjim had the heavy duty version. and were not noted on tag as such anyone know if this is true? I am hoping it is since I am putting it in my 63. thanks

There were several different variations on 64 SJ, and only Starfire, Ninety Eight CSC and trailer package cars got the heavy duty versions.

I'm pretty new to Olds so wouldn't mind learning something about this. The 1964 options list for the 88 series and the Starfire/Jetstar 1 both show the hydramatic (M35) and heavy duty hydramatic (M37).


Specifically what was the difference in the heavy duty?

What did the trailer package come with?

Heavy duty clutch Packs.
All full size Olds '61 through '64 were Roto 10 Transmission, more commonly called Slim Jims, and some people try to call them Jetaways as well but they weren't.

No other changes to the car? Brakes, cooling package, etc?
