Fitted maybe 10 sets over the years, cortina one were a crap fit but they have improved a lot ft wise over the years, escort Mk4 didn't have any problems fit wise, sierra rear beam bushes were a VERY tight fit but they also improved lately, use wise they all worked fine for years.
Although i would pay the extra for stainles tubes, a few years down the line the standard ones look like ford made em, IE rusty lol
