Mono vs Multi leaf shock mounting plate

I bought a new 12 bolt to replace my 8.2. I also decided to switch from the original mono leafs to multi leafs (5).

Can I use the old shock mount bracket from the mono leafs or do I need to get a new one specifically for multi leaf? The part where the shocks attach has 2 holes that the shock goes between while I think the plates made for multi leafs just has a single hole that the shock attaches to from the side.

Sorry if my description isn’t the best but any help would be great. If I can use the old ones I’d be happy, they’re already here and they’re free.

Thanks,

Dennis

You WILL need to change the shock mounting plates. I found out the hard way, multi-leaf and mono-leaf shock mounts are different. The mono-leaf plates have a longer extension that puts the the lower shock mount too far down when used with multi-leaf springs. Your shocks would be too short with that 5-leaf stack of springs in there.

Initially, I modified my mono-leaf plates. But I eventually found some OEM multi-leaf plates in a junkyard and put those on. The modification was pretty simple, I just cut off the dog leg extensions and welded on a 1/2" bolt. That worked fine and only cost a couple of dollars.

I hope this helps,

Gerry

When I switched my mono 71 to multi leafs I reused my plates, but mine were CE bolt on traction bars with their plates. Only thing I did on that car was drill out the locating pin hole bigger.
