Old topic I know but is one of the top google results for cortina bushes..
Ive just ordered a set specifying 47mm for both chassis and axle ends of the trailing arm and neither of them fit :/ Looks like I need 50mm for chassis end and 43mm for axle.
Measure twice and all that.
50mm front lower bushes are late ones, rare (last 6 months of manufacture) you need to leave the old bush outer tube in there and fit the 47mm polys into it There was a time no one sold the 50mm ones so this was the only way to fit polys if you had the later bush size, worth doing if you cant wait for the seller to send the correct 50mm ones ?
Rears only come in one size (43mm,) it's the front bushes that have 3 differant sizes 43mm, 47mm and 50mm no matter what he seller says, Deflex started this and now all the deflex copys are continuing the mistake
