I have a 1971 Maverick Grabber with a 302 and a C4 auto trans that I’m having difficulty with. The starter acts as if it is not fully engaging with the flex plate and slipping. I have a Durablast #DL3124 in it at the moment. I was told to see if I could find a starter with a longer bendix nose cone. The Durablast has a 2 ¼” cone. I looked into see if Durablast has a longer cone, but no. I then checked into BBB starts, but still could not find a starter with a longer cone. Has anyone experienced this before, and do you have any suggestions?
