First post... Been lurking for awhile. This is a great community and the information here is invaluable.
My Brother @tuckero23 and I (and my 9 yo son) are slowly working on a '62/75 FJ40 frame off resto/lite-mod. This 40 is a clean 62, but was "upgraded" to early 75 running gear, 4 speed, and 2f engine. It had also had a SOA lift and the front axle has been cut & turned, to approx 12 degrees of pinion deflection. We are trying to keep this build relatively stock spring geometry, and are going with an OME 2.5" suspension set up in the original SUA configuration.
So my question is what pinion angle shoud we shoot for with this set up? The current angle looks pretty extreme to me, and we are thinking we should do the old re-cut & turn back the opposite direction. Should we go as far as a complete mock up and measure/tak it up, then weld up? Or should we be able to do it on the bench to 6 degrees ish? Or, just buy a new housing and start from scratch?
I have checked out the cut & turn thread in the stickies. Looks like the stock angle is 4 degrees.
Thanks for any input. I will get a build thread going here pretty quick, have a ton of pictures.
