Does someone in the Salt Lake City area have a spring spreader for the rear spring of a Model A Ford?  As I understand it, these are somewhat different from those used in 32-48 (?) Fords because the spring is positioned directly above the axle and the differential housing prevents a straight line between shackle eyes. 

I made something out of a couple of 2x4s to keep the spring spread out while I replaced the rear axle in my 29, but the spring tension caused the ends to collapse slightly and as a result it's left the width of the spring about 3/4" short of allowing the shackle to be inserted.  I know there are other ways to do this, but in a discussion with a friend, the idea of asking here came up and I figured it's worth a try.

Thanks,

Ray:

   I have a friend that will readily allow me to borrow his spring spreader, but I've never needed it.  Here's how I do it:

1. Carefully disassemble the spring (use a couple of heavy c-clamps)
2. Set the main leaf on the axle with 2x4's under each spring perch.
3. Put one shackle in.
4. Use a big clamp to slowly compress the spring.  I use a large metal "Quick-Grip" meant for woodworking.  Rather than using the clamp to compress, I carefully bounce on the spring and just take up the slack with the clamp.
5. When the second shackle holes line up, insert the shackle.
6. Using a piece of all-thread for alignment, use the clamps to recompress the spring clamp.

Total time, usually about 20 minutes. 

Oh, I always replace the old, used spring bolt with a nice new grade-8 socket head of appropriate size.

I don't have to say be careful do I?

Well, I'd hoped to do it without removing the rear spring, but that might not be possible.  This is a genuine rat rod and the main spring bolt is (at least at this time) permanently attached to the crossmember (some previous owner welded it in place.) I spose I could back up 20 yards and remove said spring bolt, etc., but I was sorta lookin for a shortcut so I can get this critter back on its feet and make some room in my garage for other projects.

Hmmm...time to think this one over a bit.  And no, I don't need to be reminded to take care with springs.  I've had my own "learning experiences" with 'em.  Thanks, anyway.  Smiley

one of the "mags showed making one out of a tubing with a flattend end and and nut welded in the other for a bolt with long threads--make somehing "safe" for the bolt head to work against on the other end..

Yeah, there's a Utah Model A club.  They meet in Ogden.  I've met a couple of members.  However, looking for it on the web gave me a phone number and I'll follow up on that.  Btw, there's a chapter in St. George.  It's on this page:

How about Hugh Coltharpe, he is in SLC area and should have everything related to hot rods. He is the treasurer of USFRA.

Well...I looked there, but didn't find him exactly, but I sent an email and perhaps it'll lead me in the right direction

Thanks,
