47-55.1 1949 GMC panel truck...what company makes ladder bars or caltracs ?

[1949gmcpanel]

Would like a direct bolt on kit for ladder bars or caltracs. For my 1949 GMC panel truck.
I have a high HP engine and need a good ladder bar to launch on slicks without axle wrap etc
.

I have a Ford 9inch with stock leaf springs with lowering blocks.

What companies sell a bolt on kit that would work to help me get traction?

I cannot use slapper bars since they are too low too ground to clear speed bumps etc.
