Yep , your right to fear , been a while since I did a 773 but the T190 , 200 , 250, were all about the same , it can go fairly easy if the nuts holding the air bolt unscrew, and it can be a nightmare if the bolts are rusted up which they usually are and the bolts spin , , when they are rusted up I cut them with a side grinder and cutting wheel , you have to pull the insulation from behind the seat to get at the heads if the bolts and they are carrage headed bolts , when going back together it helps to have someone help you hold it up to start the bolts , something seriously wrong with my link to this site , can only post in subject section , not in the message section but can post and paste
