Clutch diameter differences?

You can use the 10 inch scalloped Borg and Beck clutch and pressure plate for the heavy duty police/taxi or truck that fits the same bolt pattern as your standard clutch. All you need are the special pressure plate bolts from Brewers Performance. You can find the pressure plates, relatively inexpensive, on eBay. It is different from the 10 inch diaphragm clutch system cjh has. That system looks very sweet and I almost ordered one for my 273.
