Electric Power Steering conversion kit question

A member here (Haven't seen for many months) did that EPAS kit to a 68 Valiant.
Apparently it works fine. A friend will be soon installing the same on his 50 Dodge with a small block.Not much under hood clearance.
I need to do the same with my Belvedere. Cost will be about the same as a Borgeson unit.
Can't make up my mind.......
