Hot Rods What rear spring for a 40 rear and halibrand QC?

I am about to modify my 34's rear crossmember with a model A center section. What spring do I need to use with the 40 rear end? Model A or Model T rear spring?

Thanks,
Rich

 

model A is taller than a T, id be shooting for the T spring myself.

 

I'm using a Model A spring and cross member with the '40 axle/Halibrand in my '32.

 

A will fit the A crossmember better. You can finagle how high the crossmember is to get your ride height.

 

Use the spring made for the crossmember. I'd use the Model A myself.
