Wrong U-bolts??
Hey fellas, So i got around to installing my front axle today, and the U-bolts i bought from classic haulers will not fit my plate and springs, and are almost 1/2" too narrow to fit in the axle holes. Has anyone had a similar issue? the part # is 2875. I have 2 new ubolts from either dennis carpenter or Sacramento vintage ford that came in a box of parts i bought off a guy. They are for stock springs and even those don't really line up with the axle holes without a little persuasion. i can't use them though because i removed a few springs.

I sent an email to classic haulers. I just checked out speedways u-bolts and they list the measurements. Seems like speedways would work even though it says for stock springs, they are longer in length so hopefully theres enough threads since i removed a few springs.

this is what my ubolt plates look like.The ubolts from classic haulers will not fit over these or my springs. the other ones i have will.. but they are for stock springs. i might try it and see if there's enough threads to bolt it up.

He's saying 1/2" width difference though, sounds like a lot? A pic would help probably. Local (big) truck repair shops or spring shops should be able to make whatever size U-bolts you want while you wait.

just put some on last night from the girls in AZ for the lowering springs the fit fine. I also lined them up with the old ones and are the same with. Like the iowa guy said a large truck shop can make some in a heart beat. Good Luck.

1/2" at the ends of the legs just doesn't matter, just spread/squeeze them (not easy admittedly). What matters is the width between legs at the top. I've had custom u-bolts bent, and only one of the four went thru the plate holes without "persuasion" or outright bending. Very hard to bend them so they are exactly 90* after springback.

Yes, that's what I mean, at the top or shoulders is what counts. If they are 1/2" too narrow at the top they can't really be made to work any way I can see looking at the pictures. Let's see a pic of both kinds of U-bolts so there's no confusion.
