Astro Performance Warehouse 800-343-0056 claims to have carbon fiber blockers. That phone number is no longer in service. Does anybody have a good phone number for them? http:www.astroperformance.com is currently under construction. No phone numbers listed!
I'd buy Carbon Fiber Blockers if I could get ahold of them.
I had Brass Blockers in my early model 5-spd, & LOVED'em!!!!! I think that Carbon Fiber would hold up like Brass, yet offer the smoothness of Fiber. Course, that's just my opinion.
If anybody has a good phone number for Astro Performance Warehouse, please reply here, OR E-mail me.
