The attached link should give you a idea of what parts are used in the Renegade kit. You listed all the right parts. The t/o bearing is different than stock 901 piece and appears beefier. None of the parts used are chevy products.
Flywheel appears to be customized from the extra machining that I noticed. Might be from a 911, bus etc. but I'm just not sure. Same goes for clutch and pressure plate. Sorry for the vague answers but best I can come up with. I'm sure Brad can identify them all.
RH offers two different clutch packages, a standard and a 9" upgrade for those running a little more power. I seem to remember Scott saying that the 9" was now all that is offered for the 914.
There are several places around the country that offer these parts for 901/sbc conversion and I believe you will see several differences depending on where and when these parts were produced.
