Hello, I have a 68 firebird that I would like to covert to quick ratio steering.  Any suggestions out there??  What has worked for you??    

The WS=6 box from the 78-81 TA's is a bolt in but are getting very scarce. The FE4 box is from the 91GTA and is also a bolt in and is the quickest ratio box GM ever made as far as I know. Rock Auto sells them brand new in the Delco box and has the best pric. The only modification one has has to make on the FE4 install is the power steering hoses where they attach to the box have to have metric to SAE adapters installed in order to use the original power steering hoses. You'll love the box!
