I was flippin' through the Dennis Kirk catalog and happened by page 168 and saw the price for handle bars and about fainted. The cheapest was $34.00 and most were around $65. I will offer this bar for the RXL. I've used them on all my recent sleds. They are 27.5" long which makes them a bit longer than most sled bars. You get more turning leverage that way. The pull back is 3" and 7/8" diameter of course. They have knurling from 2" to 5" from center and best of all they only cost 29 bucks. Have me toss one in when you get a hood.
Say on the seat issue. I won't be able to supply seats because to fit the small and large tanks would really run the cost up. Two models plus the mold coats for foam would drive the price out of site. If you have good foam, do a search on ebay as I just did. They have some pretty nice seat covers some with tunnel side knee pads. Now if you want to be as authentic as possible call Conrad Van Batavia in Verndale, MN. He makes RXL seats and I'd guess if you sent him Indy foam and seat base and told him you want an RXL style seat he'd make one up for you. His number is 218-639-1815.
I've heard noises from my mold maker so I know he's working on the RXL molds.
All for now.
