Searching here on Moparts here's what I find.

If you have the correct return spring bracket part of the problem is that the negative battery cable is attached to the block in the wrong location.
(providing that this pic is correct).

Supposed to on a 1970.


The tab on the bracket goes in the hole in the cylinder head and the ground cable goes under the intake bolt same as the bracket.

Another style of bracket.
Supposed to be a 1969
