I have been getting some conflicting information about the conversion so I need to hear from the experts. First I was told that you can't put multi leafs in a '67 because the axle perches are in the wrong spot. Then I was told you could but all you have to do is grind down the springs a little because they are a little wider than the monos, but the perches are in the right spot. Does the factory traction bar have to come out? I need a clue.
i converted mono's to multi in my 67. i used the original perches, just needed a diferent set of rubber bushings to go in them. traction bars are of no interferance what so ever. sounds like the info you are getting is not for changing the springs, but the whole rear end.
I've got a 69 multileaf rear end on my 67, installed by previous owners. I can't say the factory traction bars need to come off or not, but you can do without them OK since the multileafs will be less prone to spring windup under hard acceleration. You may need to get multileaf front spring perches (available from all the catalogs) but it doesn't look like any modifications are needed. The spring to axle attachment may be tricky - somebody else will need to talk to that since my springs match my axle. You run into wierd problems with the anchor plates due to 68/69's having staggered shocks. I wasn' t able to find multileaf anchor plates for non-staggered shocks. I ended up using 67 monoleaf anchor plates when I removed the aftermarket traction bars. The lower shock mount ends up lower but seems to work OK. My car came with aftermarket traction bars that bolt in place of the anchor plates which may be something you'd want to consider.
I put multi leafs in my '67 15 years ago. I ordered from Benz Spring and installed them myself in the original perches. Traction bar did not need to come out.
Thanks for the replies. From what you all said, it seems like I can do the conversion without any cutting, welding or any other craziness. I was hoping to hear that.
