^^^^^^If you are talking about the wishbones they are 46-48 Ford style that have been drilled and sleeved. Speedway sells the straight version with or without holes. I can't see the axle but CE or SO-CAL make a nice forged one.
I'll agree with Lynn especially his use of the word "style". The stock Ford is about 6" from the perch pin to where it starts to dip measuring at the top. These look to be around twice that so probably have been lengthened before making the drop. Plenty of fab work in those.
X2 on the Bones. I used those to re-triangulate my 35 rear end on my lakes modified T. The drop worked well with the back of my body. Pretty stout bones!
The guys nailed it on the wishbone but on the I beam "axle" you can't see enough to tell except that it appears to have been polished and or chromed. It could be an original Ford axle that has been worked on or it could be an aftermarket axle.
I hadn't seen that photo when I made the comment on the "polished' axle but I'd believe 31Vicky with a Hemi hit it pretty close to right. I don't have a photo of my So Cal axle handy to compare at the moment. And hell, I just got new glasses a few months ago too.
