CLUTCH GRINDING NOISE / BH MISALIGNMENT

* My transmission is an original A-833. The BH is the original 482.
* I used an old input shaft purchased from Brewer's, as an alignment tool. I found out the hard way last summer about the inaccuracy of the plastic alignment tool.
* I'm sure the bearing retainer and bolts are original. I don't know if the rebuilder (Liberty's Gears) used the original snap ring on the input bearing. I'll have to check on that. Could the replacement snap ring cause any problems?
* Flywheel fully seated - I think so. I scuffed the crank flange and the flywheel with a pad on a die grinder before installation.
* I don't know how to check if the transmission face is parallel to the rear of the block.
* Both clutch discs seemed to slide fine on the input shaft.
* I don't know if the 2 faces of the BH are parallel or if the hole is concentric. I don't know how to determine this. I had the BH bushed at Brewer's, but I doubt if they checked those surfaces. Speaking of which I suppose the block surface doesn't necessarily have to be square, does it.
* I called Wayne Brewer yesterday to order a new flywheel. He wanted me to use the dial indicator on the surface of the flywheel that the clutch rides, instead of removing 2 bolts and installing the DI in that recessed flange. I haven't yet been able to get the DI I ordered from Summit to fit on the clutch surface and clear the underside of the BH, even though I've been cutting the rods.
* I'll try to install the transmission with no clutch and PP soon. When I remove the BH I'll also make sure it fit's on the bearing retainer.
* That's a good point about clearancing the BH bolt holes...for future reference.

Thank you gentlemen for your sage advice. Let me know if you have anymore pearls of wisdom. When I get this resolved, I'll post what the solution was.
