Long style clutch pressure plate.
No adapters and nothing modified. Original bellhousing with casting numbers that came back as a truck with v8.
1.635-1.700" total length (roughly)
3.00" O.D. (total outside)
2.63" O.D. (bearing face only)
1 1/16" 10-spline input shaft
The throwout I have looks similar to the original we have been dealing with. Only difference is that the I.D. is way smaller. I understand what you are saying about the bearing being separate from the hub. The clutch we got the other day had a bearing that had to be pressed onto the hub.
