68 Barracuda 340 water pump , timing cover question ???

I bought this balancer for my early style 68 340 been working fine unless you want to spend for a better one .You wont find one with timimg line on passenger side so you have to find your tdc with a bump stop and make a line or use some timing tape.
Hopefully not a crank issue. Good luck !
