The QA-1 catalog doesn't list an extended length upper for the early Camaro/Firebird/Nova/Chevelle applications. Their pn #1210-113 for these is the standard length stud. When I called them, they confirmed that only the standard stud length (3.486") was available. The ball joint studs are available as seperate items, but again....no longer stud for that model number. Oddly, not even the standard length stud is listed as a seperate replacement item in their catalog. When I pointed this out to the Tech person on the phone, I got the "I dunno why that is." response.
That was 8 months ago, so maybe they are available now...though they are still not a cataloged item. Might be worth a phone call.
