There were no doubt many steeringboxes designed for the 105/115 series, and I have experience with only one datapoint: My '66 Sprint GT came with a non U-joint, non Burman box. I was able to replace it with a Burman box from a '76 spider, which bolted right in (I wanted the ball bearing action of the Burman).
My sense is that the U jointed boxes were only used on GTs and perhaps sedans - not on spiders. I am guessing that the length of the steering column changed a bit from model to model to accommodate the different wheelbases between the GT/sedan/spider, as well as different steering wheel designs (change in the "dish"). So, it is sort of a crapshoot what box/column will fit what car.
Does your '71 GTV's steering column have a U joint? I have owned both a '71 and '76 spider, and can tell you that the steering systems seemed identical through that era of the spider series. I know nothing about later GTVs.
