btw, did you notice the vintage metal works guy makes a new one for the bigger hole belll hsg dia?
http://vintagemetalworks.blogspot.co...bore-bell.html So he DOES make em for v8's now - BUT make sure you measure your bell housing index ring diameter - 60-66's with V8s "should" have the 4.686" dia index ring (i.e. hole) and 67-68 had the 5.125" index opening. Anyway, just shows he can make just about anything - so he can probably easily make one to fit your situation. You should have the 4.686" bell housing opening if it's the stock 60-66 bell, but never hurts to measure before you order/call to see if he can make one. You dan't have to be real precise in your measurements, there are only 2 sizes - if it's larger than 5", then you can order the part above. If it's less than 5", you have the 4.68." bell index ring, and I'd give him a call to see if he can make one up. Just an option if Hamilton is not available.
