<VV> Pressures and Petronix

[Bill Kronen]

Slow progress as the 66 Coupe goes back together and questions arise. 1. 
Does the tire pressure differential apply in the same ratio when you 
have 205/60/R15's on the front and 215/60/R15's on the rear?  2.  Had 
bought a Petronix II and Coil to go on the Turbo Spyder
but would now like to install it on the 66's 140.  Good choice or should 
I save it for the Turbo?  or buy another?  Help and opinions always 
appreciated.
