Need a little help please

[SinnedSpeedShop]

Hey fellow gearheads. I purchased a 67 for its rear suspension. It’s a few states away, I won’t be able to get it for a while and I was wondering if someone would be willing to give me some measurements so I can at least begin to fabricate the frame it will be going into in the meantime.

What is the LENGTH, WIDTH, and HEIGHT of the trailing arm crossmember?

If anyone could help me with these measurements I would greatly appreciate it!!!!!
