Much appreciated for the figures....I found my Manual this morning. Now I just need to do some research to figure out what oil is best. The book seems to recommend ATF, but there's been a lot of discussion about what to use.
I tried a coupla different oils before I settled on 20W Motor oil for my 1964 and atf for my 71 tbolt I,m 205-210 5 11 the tbolt is a bit more twitchy /responsive then the 64 but I got used to it later pal
That's interesting, I find the OIF's to have much slower steering and turn-in. They do have quite a bit of rake out of the box so tend to understeer quite a bit, though that can change with different spring rates and shock lengths.
