i used to have a book that showed the shaft length difference between std. and deluxe reg. i found out about a guy that has a pile of 68,69 doors that iam going to look at sat.,and iam hoping there is going to be some deluxe regulators in the pile! any help? thanks guys!

The longer ones will be for the deluxe panels. Not sure of exact measurements but a search here should turn up something. I know it has been discussed.
Good Luck.
