Is this the right battery hold-down for an '01 CLK?

No room to install it or is the battery too big?

That is not the stock method of securing the battery. Who made the modification?

What do you mean? It a convertible with the battery in the trunk.

im baffeled as how its supposed to fit (that metal peice)

If I were you, Id go to napa and get a univercial battery mount... They're bacicly $10 threaded hooks, and a connector bracket. The hooks hook onto your battery tray, and you can use it.

Can you put the bracket approximatly where it should go? I dont know the car, but it might help someone else

Thanks but I don't think I'm going to NAPA to put some "universal" part on a $20K+ Mercedes. BTW the Mercedes part was only $5.

How bout some duct tape, or mabey a bungy:D

Dont mind me, im just tired

there are two available, the one you have is for the much smaller 74 AH battery, since you have the larger 100 AH battery, you need the one with part number 129-895-00-70 it is much shorter.
