Default Materials for powerglide crossmember

Hey need alittle help. I am making a PG crossmember basically

2 L brackets made of mild steel plate - bolt to frame mounts

~ 1 5/8" DOM seamless tubing between the two

1 - bracket for the transmission
2 - brackets with fishmounts on on end to attach trans mount to seamless tubing.

The DOM is .120", what thickness steel should I use for the flanges?

I ordered some metal from metal express in Baltimore and was pretty inexpensive...

1 5/8" DOM .120 wall
1 1/4" DOM .120 wall
3/4" DOM .120 wall
3/16" plate steel
16g and 11g steel sheet
1 x 2 .120 wall rectangle tubing

.

I'm a 1/4 inch fan, but I got a bunch years ago and have been using it for everything.

Why L brackets, I would plate the ends and bolt those to frame.

Another tip we always do for NON-full chassis cars, poly trans mount, a bunch of people used solid mounts and would crack cases. Good luck.
