340 who's balancer?

Alot of balancers do not fit correct and will end up either hitting the front cover at the timing marks before it is seated or they are too think and you need to space your accessories. I have used the Rattler before and it fit perfect.

I have the TCI rattler and it fits the 1970-up timing cover perfect. The factory crank pulley also lined up nicely as well. I'm happy with it. :)
