I would have most certainly asked for 3dr ones for you. I suppose there's no chance that you have the packaging still do you, as the reference would tell me what they sent you?

I only have Sapphire 4x4 ones in stock at the moment at Powerflex seem to be working on a 7-10 day lead time at the moment due to the show season....

However, I would still prefer you to measure the ARB to confirm for sure and I would see what I could do regarding lead time .
