[59chev]

I am going the be running the CPP under floor master Cylinder in my 59. The location of the master cylinder puts it right below the front seat riser in the cab.

I assume that the front seat riser provides structure and stiffness to the cab floor. What have you guys done for filling the under floor master cylinder?

Could I cut through it to create an access door if I built in some support from underneath with some box tubing?

Thanks.
