what spindle and brake for tbucket build?

So ive got to ask but should the panhard arm put put on after you set the drivetrain? I feel like the weight should all be on the car already so you can set the panhard arm level to the axle.
In theory yes. In reality I believe the amount of change would be so slight that it's not worth worrying about, your mileage may vary.
 
And there's always a Watts setup too. Much less side to side movement.

If vertical height is an issue you can lay that bell crank flat or in the horizontal plane. Will also work above or below the rear end housing. I like a Watts Linkage much better then a panard bar especially when the bar length is short like most T Buckets are. Just another way to get from A to B.

PotvinGuy, That front end looks interesting. What kind of rack is that you are using for steering. Also the panhard is hard to spot in that photo got any details?
Rack is Honda Civic in front crossmember. I cut off the Speedway panhard and made this contraption:

..it's based on a Watts linkage. Axle can move up and down and tilt, but no horizontal movement at all. IMG_0043.JPG
 
Panhard rods are meant to be set level. Level is dictated by the height of the axle pivot point of the bar being at the same height as the frame pivot point. The angle, shape or contours of the tubing between those points has no bearing on what is or isn't level.

The J bar on a short bracket is no real difference geometry wise than the obviously wrong angled one shown here.

J bars are useful to allow working clearance for the housing etc, but they still need to have the pivots at the same height to work as designed. Of course you can fudge it a little but the closer the better.
 
The shape of the bar makes no difference. It’s the two end points that make the difference. The amount of movement on the rear is not drastic because of travel of the suspension is so limited. . The front with cross steer is more critical.

You guys explained it better. The two mounting points as similar in height as possible.

The panhard rod is a bit squirmy but the mounting points are aligned. That’s the important part!!!
