looks like there is some fourbar/ wishbone rods mounted at the s-curve of the axle
what i dont get is, on the left spindle there is a stearing arm at top of the spindle .
With what apears to be a stering rod that goes to a stearing box at the firewall somewhere
like a regular stearing
But then he have a rack-n-pinion stearing mounted on the axle
I like the "face" of the model-T with the stock shell and stock headlights
To nit-pic he dont have the Ford "smile" on the I-beam axle, but on the other hand
Ford dont had the smile before Model-A. And i should not had put lightening holes
outside the springs with that heavy engine
Do you have any pics of the rear suspension? Looks like it is a IRS based on a Quick change
with a Model A spring
