Upgrade brake kit to stop spongy pedal?

Hello,Anyone know how to cover the 96 5.7 tahoes to have a more firm pedal? I heard there is a way with an adapater kit and a larger MC like from a 2500 or so i can stop this darn spongy pedal issue

Get a MC for a new body style... It requires one adaptor for one of the brake lines and it makes a big difference in pedal feel.
