67' rear 9 leaf install
Body is off the frame and I'm putting chassis back together. I'm at the point where I'm putting the 9 leaf rear spring back on. I've read some prior threads about people using an engine hoist to pull the spring up to the bolts on both sides and others have tried a jack. I don't think I can pull straight up on the spring using a strap and hoist(cross member in the way, etc.). If I try the jack then I believe I will need some C clamps and blocks of wood on the spring so the jack does not slide up as the spring is compressed. I'm just looking to see if there are other techniques to try?? Also I know you don't torque the 4 bolts to the diff cover until the body is back on...so do I just snug the spring plate to the spring??...as i do one side will this cause any stress to the 4 bolts that are going up to the diff cover?

Re: 67' rear 9 leaf install
Yes, you should use vice grips or C clamps near the end of the spring to keep the 'lifting device", jack etc., from slipping.
With the body off jacking may be difficult due to the lack on weight on the frame. You might try setting the jack on top of the crossmember. Put the pad of the jack on the outboard side. Put a ratcheted tie down strap around the spring, (just inboard of the spring hole) run the strap up and around the crossmember and on the jack pad. Draw the strap tight, then slowly jack up the jack. This will tighten the strap and pull the spring end up. Insert bolt and fix bushing & nut.
Just snug up the four bolts for the spring. It won't go anywhere. -

Dave A easy way is to put a 4X4 between the frame and the garage door opening frame . then jack the spring up with a vice grip to keep it from slipping . easy one man job .Comment

Re: 67' rear 9 leaf install
Dave push the frame under your open garage door opening (if you have a lift that will work too) . Put a long 4X4 between the rear cross member and the upper garage door frame. put a floor jack under one side of your rear spring and jack it up . The 4X4 will hold the frame down . I use a vice grip in the spring to keep it from slipping on the jack . You will need a second person to hold the board in place before you jack it up .
My brother put his on with a ratchet strap by himself ...Comment

The pry bar will not move. I have removed dozens of springs this way and helped other members to do their cars. Most guys reply is "that silly its so simple". and yes it works best with two people.Bill Lacy

Re: 67' rear 9 leaf install
Hi Dave,
Here's a picture of a slight variation of the methods discussed.
I wish I'd known about Gene's use of a piece of chain to keep the frame from raising up as I jacked.
I used some boxes of magazines and about 5 bundles of roofing shingles as weight.
Maybe you'll see something you can use in your situation.
Regards,
Alan
Note it's a "learning" experience… first without the extra block in the head of the jack and then with the block!
