Chief,I recently bought a 1987 Raider with a broken windshield however it came with a bunch of extra parts one being a new windshield,so I had some glass guys come out to install it, and when they removed the windshield wow was there a lot of rust, looking back I wish I would have removed the windshield myself,sanded it down to bare metal, primed,painted then come have them reinstall it, or I guess I could have had them leave and come back but oh well, its just a plow truck, you may not have that problem since your in Al. and Im in Neb.As far as the carb. goes I purchased a 32/36, from what I read on here that fit my needs best, however the day the carb arrived it started running and idling perfect so I haven't installed it yet since there were higher priorities, but since your already bored out and going to install a header, sounds like you'd want a 38 IMO. also from what I read get a 3-5lb. pressure regulator and another fuel filter Good luck!!!
