dont know about a longer uj. i cant remember the difference in length now ( it wasnt that much maybe a couple of inches) it was ages ago when i was messing about with it. i tried the non pas and pas uj joint but it didnt work with either of them. i thought about cutting the steering column and sleeving it to extend it but in the end i couldnt be bothered and refitted the pas.
so if i wanted to fit the non pas rack i needed to get hold of a steering column off a non pas car, unfortunately this had already been removed from the car i got the non pas rack from.
