A/c hoses - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So now that I've done my LS swap, I need new a/c hoses. I have a vintage air sure fit kit in it and I want to go with Aeroquip hoses (in case I need/decide to change things down the road). My question is, what size AN hoses/ fittings do I need? My understanding is that 8 AN is the same as 1/2" which is the size of the low pressure side, but what size matches up with 11/32" (high pressure side)? Do people just go 8AN on both hoses? 6AN would be 3/8". That seems likeNit would be too small. Any advice is appreciated! I'll probably call vintage to confirm with them. Thanks!
