Okay and the spools aren't that expensive on the end of the day... I am
going to have three choices of gears for Speed weeks.. and three sets of
tires... I have the 28" Goodyear's even after seeing yours I bought a set..
and the 25" street tires... and I am looking for a good set that are in the
27 range... like a short track Nascar tire except it is only 9" wide...
designed for the Hobby stock class of circle track...

I am still looking for a 2:47 9" ford set... my basic gears are   2:75  
3:00   3:25  right now all but the 3:00 set are open gears... I'll order
and install the spools and check that out... Thanks Keith
