Hi guys. With all due respect to Ivy66GT, who always gives good answers, the no hold down is not a good idea. Heaven forbid that mwillis should ever be in a front end crash, that battery would go flying and put battery acid all over the place. I have a friend that that happened to and lost an eye. I put the conversion that jspagna1 suggested in my 66 coupe and it works fine and did not take that long to do.
