Just bought a 74 1/2 TR6. Not my first rodeo though as I've owned a '69 and a '73 (sold in '94). I must be going through male menopause. It's nice to be able to pop the hood and know what I'm looking at! 73,000 original miles, needs a new top and paint among other things. I plan on asking a lot of questions. The first one being the difference in handling between a 185r15 and a 205r15 tire. Is there any? Have found two dealers for the redline tire; Coker and Universal. The Coker tire is about $30 cheaper. Glad I found this forum and I know I'll learn a lot from you guys.
