T-5 clutch kits...

180 is probably a little high for a stock clutch..I would go with the King Cobra for near the same price. BlueOvalindustries (also has ebay account) sells the King Cobra for 179+Shipping. It does come with a throwout bearing.
 
I paid about $180 for a clutch kit from Ram. 10"er, includes the pressure plate (diaphram) disc, throwout bearing and alignment tool. I have a mild 289 and clutch works great. I went from a 3 finger job to this diaphram and its so easy on the leg.
