what is the best buy for a single disc cluth. I have a 97 4x4 ext 2500, custom plate , lpugged wastegate, 4in straight pipe, an some gov. work, and 4. 10 gears. I drive it daily and don't like the cost of a dual disc where i would have to replace the fly wheel. nm The clutch may not make it through today. Please help with any suggestions. Thank you.
