Getting rid of some leaks on my son's 73 Dart Swinger and after removing timing chain cover there seems to be some slack in the chain. Where can i get a timing chain tensioner ? Part number ? We rebuilt this 318 engine some years ago with a new double roller chain and sprocket set .I think this is a simple bolt on deal .Timing marks still line up just want to take the slack out of it before it gets worse .
