my cranks i have here, the manuals have the hump on them. i think all the earlier cranks may have had them. uses that to support the flywheel on the manuals. on the later one without the hump, the converter wont work with the hump. flex plate wont work with the hump also. the pilot hole is different with the later one also. same size pilot on trans/converters, different bushings between the 2. its complicated to explain unless you have an early and late crank next to each other along with parts to see the differences. i should get pics and stuff of the differences i guess... dave stohler www.picasaweb.google.com/das24rules _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
