Well, I have most of the info anyway. I have negotiated what I believe is a good price...if you don't agree, sorry.
Anyone who wants just diaphragms, I have negotiated a price with Sirius Consolidated, here in Kitchener, Ontario, Canada. They don't deal with the slider kits, just diaphragms. Regular price for a set of four was $89.00.....we can get a set of four for $60.00 US or $15.00 for one, if you don't need four. They will ship to anywhere in Canada or United States for $5.00 per order. If you want to order from them, direct your email to Martin at this email address: sci@siriusconinc.com and indicate that this is a VentureRider order, for that price. Their part number is called SD-1
I am working ( slowly through emails ) with an outfit called Carb Kit Capital for slide assemblies but haven't got a firm price from them yet. I'll post that when I get it.
