Hello??? REICHLE, CHRISTOPHER

I never heard of this magazine before it showed up on my doorstep the 
other day, but on page 93 of the July/August Grassroots Motorsports is an 
ad from PaceSetter Exhaust Products is an add for Armor Coat headers. No 
mention of available types. There ad is opposite one for Moss. BTW the 
issue has a short article on the Carlisle meet (they sponsored the Sunday 
AutoX) and several good article on LBC's. If you haven't heard of it 
check it out. Think I'll keep it.
