Eaton Springs (Detroit) are the best springs. They will tailor-make any spring you need and they will fit the car perfectly. You will need different mounting hardware over the axle. I believe the perches are the same, but one of the others will know for sure.

I changed from mono to mulit leafs on my 67 bird a while ago. The perches are different. I had a spacer made so I wouldn't have to change my perches. Wasn't exactly proper and made locating the sprongs a pain. I'd check into putting the correct perches on your rearend.Just my .02.

I have a '68 rearend housing that has the perches still on it I would give you if you pick up or pay shipping. Would need to be cut off & welded on your rearend.

I have been looking at doing this myself. A couple of options not mentioned were the 3-leaf mono replacement springs. JCWhitneys and others carry them. Upgrading to an 8.5 rear-end out of a 73-79 Nova is an option as well, stronger, parts cheaper and same width. Besides the springs, is changing to the different shock mounting location from 67 to 68 & later..

I was waiting for that answer Tom... should have known... either you, Quenton or Bjorn....

I'd got with Q's suggestion, have a replacement set made by Eaton, and you'll be almost as good as multi leaf, but better than new! And no pearch problems...

that seems like the easiest way out.
