Ammo,
I had uprated U/J `s fitted to my prop a couple of years back. Sorry I cannot find the invoice but it was all done by Chards , 1 Cole Rd , Bristol.Tel 0117 9717341 IIRC the cost of the bearings and a full balance and repaint was £80. The guy commented that the original u/js were the cheapest/lowest spec available and not up to the job. My prop was also bent by 3mm and out of balance by 20 grams at one end. Excellent service from Chards
