SCDaytona,
Pictures of big wheelies DO NOT prove that a car is 60 footing well, you are correct...we just LIKE posting said pics of big wheelies whenever there is an excuse to do so!!!

For the record, I've NEVER converted a 727 car to a glide, I have, however bought 3 mopars that already had glides in them, and have been happy with their performance. The biggest difference IMO is that the convertors for a glide are vastly superior than anything available for a 727/904
