The part number you have listed for the service manual is quite old, the new part number is LIT-12618-PZ-50. And I do have this manual, it does not give a complete list of springs and weights and only list a couple of them. Your dealer should have a spring and weight listing that is in the Tech Update bulletins, but they will be from way back in the early 90's. So either your dealer has not dealt with snowmobiles that long or they are not that great of a dealer.

Also I have 1 of the 3 pages from the Tech Update bulletin regarding springs from 1988 on my website showing all the springs available at the time, I still need to post the other 2 pages when I get time to scan them. The first and second page show primary springs and the third shows secondary springs. Most of these springs are usable on a Phazer.
Go to
http://www.zenitram-inc.com/kgmz.htm
and then click on the Phazer manual button.
I wil try and get the 2 additional pages posted in the next couple of days.
