There is a swap meet vendor that has started to make (modify) 'bumped' covers, a reasonably decent job of replicating the factory bumps, BUT NO coil mounts. -- Paul Holmgren Mine: 2 57 300-C's in Indy Hers: 05 PT GT R/T HO Stage 1 Hoosier Corps L#6 ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to: Chrysler300-unsubscribe@xxxxxxxxxxxxxxx For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/Yahoo!
