I like Borgeson products, and their conversions. But a set screw on a steering shaft (or their U-joints) is where I draw the line in safety. If a person's EPS goes out (which they can/will do), or the vehicle/engine stops operating for one reason or the other, Or even needing to move the vehicle if the battery goes dead ...or what if an engine mount breaks on that side, will the engine lift up enough to pry the set-screw joint apart?? There are times where there could be a LOT of twisting torque on those shafts.
You should be able to build up a whole new shaft from parts which is safe, low profile, and doesn't use set screws. Summit Racing has a whole bunch of steering parts that street-rodders use to make up steering shafts. Street Rodders need to go around headers and connect different makes box/columns, etc. Summit and a couple other sites (google it) sell all number of steering joint ends, slip shafts (so you don't get skewered), shafts of different or cut-able lengths. Different splined ends to fit different make boxes. And various u-joints. They're not even all that expensive all things considered. Use all-steel if you can so you can safely weld it all up.
