I could use Kadron linkage and air filters,Let me know if you have anything for sale. Regards,Jim

Not sure if this is what you're looking for or how much you're wanting to spend, but I found these:

I use the CSP linkage on my bus and it is awesome. In the words of Ron Popeil, "You set it and forget it". I have never had to adjust it and the quality of the fit and finish is outstanding.

I've got the Scat linkage for Kadrons for $52.00
The factory linkage works OK if you are really good at tweaking stuff...
The filters are available at NAPA, tell them #2087, and give them your measurements, just to be safe (there are two different heights, depending on your setup).
