When did Toyota start using wider spring perches on the rear IFS axles? I know about the difference between '85 and '86, but sometime after '86 they went even wider.

I'm trying to swap in a rear axle from the 90's and the u-bolts won't fit because the perches are wider than the holes in the mounting plates. <img src="/forums/images/graemlins/zombie.gif" alt="" /> So I need to look for new mounting plates and want to know what years to look for.

No, I don't want to do a u-bolt flip if I can help it as this is on my daily driver and I don't want to have to screw around with changing shock mounts, etc.

Its only some of the 90's trucks, not all. I think RogerB has some info on those... ?

Yep, some of the 3rd gen pickups ('89 or later) had the wider perch and the rubber lined clamp to hold the springs. One option is to grind notches into the sides of the wide perch to fit the narrower u-bolts and spring plate, or cut off the wide perch and weld on a narrow one, or get a set of wider bolts and plates.

Thanks for the information and suggestions. So Toyota had both styles in the 90's? Weird.

My '89 single cab short bed truck came with the wider perch.

I looked at grinding notches in the perches to fit the narrower ubolts, but it would have comprimised the end bracing of the perch and I would have had to fab up new bracing.

This is my dd and I really don't feel like spending time messing around with it, so I am still looking for a set of spring plates.

Someone must have a set of these lying around after a ubolt flip... Buller???
