Are there any websites or pages that show the differences between the 40 & 45 LWB frame? I'm looking for specific info, maybe pics and dimensions.

Thanks, Matt
 
oddly all the 45LPB frame specs seem to be incorect, at least in the stuff I have.
 
on my old 45 pickup i could see the weld seam where toyota added the extra foot of frame(or what ever it was)

Some factory service manuals have it. PM me and I'll scan and email for ya if you want. I got a 75 FSM.

There's a thread way back that has a little of what you want. It's here in "mud" somewhere, but I'm not about to go try and dig it out. I don't even know what it would be posted or searched under. Somebody posted a pic of their 45 frame with the factory cuts on the 40 frame with the addtl. metal welded in. That was before Woody's last change-over so the pics might be toast anyway.
 
Flyinglow, I sent you an email. That would be great if you could email me any specs you have on the 45 frame.

Folsom50 or anyone else, I think the thread your describing is exactly what I would like to see. If anyone has the link to the thread of pics........anyone.....anyone......Bueller........

I'm literially familiar with every nut and bolt on my 77 FJ40, but not to familiar with the 45 LWB? I would imagine the frame is not only longer behind the rear spring hangar, but also longer between the front and rear hangars? Or, did the axle mount in a different location on the springs?

Sorry if these questions have been asked before, just trying to bring myself up to speed on this.

Thanks, Matt
 
Yah the axles are mounted differently considering the 45 springs are several inches longer and have completely different spring hangers.

Bug pimp for the scans. We know he's got them.















And it doesn't matter that his junk doesn't match the specs. :flipoff2:
 
axle mounted differently on the springs (springs are alot longer in the rear)... it was a link in the tech links, a complete truck buildup, where a guy did 2 45's and showed where toyota extended the frame and X brased it...

longer between hangers and pin is centered (just about anyway) on 45 springs. main leaf is 9 inches longer too. Let me know if you need dims of a 40 frame too. I hope you my email.
 
No idea if they are accurate numbers, but here they are FWIW.
