I ordered some QT 3 degree corrected Radius and Trailing Arms for my 1981 RRC.

Received them yesterday and measured them up and the pins on them are too large. I specifically requested the narrow pins and invoice stated that was the order.

The pin size of what I received is Radius 31mm, Trailing 25mm, whereas the originals are Radius 27mm, Trailing 21mm.

Emailed QT and suggested that they had sent me the larger pin arms by mistake and they claim that they have sent the correct ones and that I need to fit a later model bush.

Does anyone have any knowledge of what size was fitted to which vehicle because I feel I am getting the runaround from this mob.
On the same day I received a full set of Super Pro bushes from Paddocks which are branded as being for a 1969-86 Range Rover and they only fit my old arms.

Sounds to me like they have sent the wrong items and expect me to go and buy different bushes because of their stuff up.

Any advice would be helpful, I have done a lot of searching on the web about sizes and there isn't much apart from people saying that some were different.
