|Fe Block||This pics shows my idea of using 1/4" angle iron incorporating the perch bolt but adding two grade 5 u-bolts. The 7/8 x 5/8 bushing will be welded to the angle iron and hold a 5/8 bolt. Once the bushing is welded, it will be cut to length. The 1 1/2" length shown is a bit too long. I anticipate 3/4" length after welded. I will need to weld v-blocks on the bracket which will cradle the bottom of the axle. I will also remove unwanted steel to make it look cleaner. It may be a bit bulky,but welding a bracket to the small 2" axle doesn't seems a good idea. An I-beam axle may work better for welding.|

A small panhard bar is fine for a buggy sprung car, the leaf spring itself limits most of the side to side movement, the panhard bar just minimizes shackle swing.
But for your coil over set-up you will want something a bit beefier, and with no leaf spring in the front crossmember there should be plenty of room for a bigger one.
Just my thoughts.... fwiw

|Fe Block||Yes, the pan hard bar is must. I was looking at the one that bolts to the bat wing and welds to the frame on the opposing side. It is available online and at Speedway. Reasonably priced too.|

|Fe Block||I'll give that mono spring some thought. As for the perch bolt, I will go back the drawing board. Although a.5/8 bolt will hold.on sh!;ear strength the barrel end. being only 1/8 thick. may crack. Maybe an under lying bracket that uses the perch bolt hole and an additional u-bolt around the axel. Welding to the axel sounds dangerous. I am not sure it is as tough as a rear axel housing as it is designed to bend for camber adjustments. I will post my next idea....Thank you!|

Ditto! Two bolts in single-shear holding the entire weight or the car's front end will not work for long...

I wouldn't trust the perch to support the entire weight, be more inclined to weld a dedicated mount to the tube axle.
Have you thought about using a different leaf type? I have a mono leaf on my '27 RPU, and a front sway bar. It rides and handles great.

Model A replacing the FRONT leaf with coilovers!
I would like to upgrade the handling on my Model A aftermarket tube axle. I plan to remove the front leaf, and install adjustable coil-over shocks. My current plan is to reverse the perch bolt and use a 5/8" x 6" bolt through the inverted perch to support the shock bottom. Any thoughts on the strength of this perch tube? The front end weights 1150lbs. (See the picture mock-up) Better ideas welcome!
