Lower Rear Shock Mount Question

[ColoMopar]

I have a 70 Duster with a 7-1/4" rear end that is getting scrapped soon. I also have a 72 Demon with an 8-3/4" rear end that doesn't have the lower shock mounts. Is there any difference in the two? Can I keep the shock mounts from the 7-1/4" and use them with the 8-3/4" rear end? If not does anyone know where I might get the ones I need? Thanks!

I believe I saw a set for the 8 3/4 for sale on here. You can use the 7 1/4 but you have to oblong the holes to accept the 3" u bolt.

Here is a set, good guy to deal with too.

You can buy the u bolts if you don't have them.
