Allen, attached is a drawing Kas sent me of an adaptor to fix the problem you
had. I never tried it and went another route. I had the crank end drilled
for four dowel pins and used the ARP bolts. The extra dowels are supposed to
take the pressure off the bolts and the bolts only have to hold the flywheel
tight to the crank. I think the ARP bolts I used are flywheel bolts from a
Chevy. I can get the # if needed. It has worked fine for me since and I now
have clutch problems. The clutch pressure plate keeps coming apart.
I was also told once the bolts have vibrated loose and worked out, the threads
in the crankshaft will never hold again. Since I used a lightweight flywheel,
I rotated the flywheel 45 degrees on the crank and used the old bolt holes for
the pins and drilled and tapped new holes for the bolts. I'm not sure if you
can relocate a stock type flywheel like this.

This is the adaptor for the TR250 and early TR6 motor. It may be able to be
used on other motors as well.
Anyone I might have missed, email me and let me know. Charly
