I have been looking to upgrade the manual steering in my 1956 ranch wagon to power steering. After several emails to Borgeson with questions regarding the fit of their power steering box, and the compatibility with aftermarket tilt steering columns, I purchased their unit. Don't make the same mistake! Their box is too large, and the shaft of the box is even with the firewall. There is no way to attach a u-joint without it going through the firewall. Talk to Borgeson after the sale, and they will basically tell you it's your problem. Talk to Ididit, and they will tell you there is no solution, and they see this problem all the time. Again, don't buy this product if you are planning on using an aftermarket steering column!
