What is the stack height on this?

I'm refurbishing a '69 Mercian. I've had the frame spread to 130 and now need to upgrade the transmission onto NOS Campag l/f record screw on hubs, currently running 13/24t 31mm 6sp-freewheel. I want to upgrade to 7sp with 28t. Will this item suit? Also which chain should I use?
Hi there,

The total overally is roughly 34.6mm.
You can use most 3/32 6/7/8spd Shimano chains.
