I just got a set of 3-leaf multi-leafs to replace my rear mono's on my '67 bird. Already have the bushings, and axle pads. Conversion kits seem to have a new set of U-bolts and a steel spacer. Do I need new U-bolts? Seems like mine have a little extra...Where does the metal spacer go? Do I really need to buy one of these kits? They all run around $90 from what I can tell. Year One's have a fat metal spacer while Detroit Speed has these thin aluminum ones, that are shaped pretty differently. What gives? Any suggestions?

Thanks!

You will find that there is a pin built into the spring pad for the 67's to keep the mono spring locked into place. I am pretty sure the steel spacer is to cover that center pin which is no longer used.

The U bolts replace the "T" bolts used in the '67 setup.

Thanks! I just got a conversion kit from Eaton for $65, and plan to do the job this weekend. We'll see how it goes...

So I just did one spring last weekend, and have a question. The hardware kit I got from Eaton came with 2 T-bolts and a U-bolt for each side. Does it matter if the U-bolt is on the outer side or inner side? I'm guessing no and am curious why they have it set up like this...

Someone may correct this but I think the u-bolts go on the outside. There they will more leverage to hold the rear. I think the t-bolts were used because the bean counters could save a penny. If you can, locate another set of u-bolts.

Does the Eaton kit come with the shock mount plates or can you use the original ones? 67's have non staggered shocks.

Well I got both done. I wasn't able to put the U-bolt on the outside on the driver-side spring because there was a small bracket to hold the brake line to the axel housing I didnt want to mess with for now. I am going to just order 2 more U-bolts and replace the T-bolts all together. It was a pain to replace these things because the rear shackles are so close to the gas tank I really had to play with the spring flex and position to line it up enough to ge the bolt through. Glad that's over! Thanks!

Oh and yes, the Eaton kit came with the mounting plates. fit perfect.
