Tested Spring sorted us with 3315, and helped techno-numpty me by explaining it all over the phone. Recommended.

I also need a pair of springs for my GND, so please contact on 01484 866907or 07870231197 once you have a price.
Best Regards,
David

I've sent you a PM

Yep tested springs they did all mine you need to speak to Murray nice guy

I asked about a small order for springs whilst at TSL Turton in Sheffield last week, they would be able to supply, and said square section are better perfoming. I assume round is just cheaper to make.
I would be happy to join in for a pair either section as they are covered by the shroud.
