Just a word of caution: the MB style hold-down does not fit all batteries.
Went to fit an MB look-a-like hold-down with the two J rods on my battery. I thought, at last a simple job that even I can do. Uh,uh Richard, not so easy.
The top of the battery (a replecement that came with the car) is made with two levels. The battery-hold frame will not fit on the battery even if the cables are removed then put back.
The rear top of the battery is lower than the front top. There is no way for the frame to fit around the battery. The frame has no place to grip the back edge.
So a simple job became impossible. I'm holding the frame and J rods till I get the next battery which will have a level top.
