I have been doing ok with the group buy on TCA's.
Only 2 issues from about 30 sets, 1 was from someone who ordered the wrong type, and the second was a metric sized bolt wouldnt go through an imperial hole
I found out a little more about your problems too
EsCosRacer, as I wanted to follow them up, to improve upon their customer service. After the first set were supplied incorrectly You were apparently asked to fax or mail over the part numbers for the components you needed to avoid further confusion, and apparently someone at your end faxed over the part numbers for Escort Mk1/2 which is why they were supplied again.....

Can you confirm that please ?
