miracle dinghy control lines

[sawman]

Having taken delivery of a new (to me) elderly miracle, I have spent the weekend prepping it for a topsides varnish and been pondering the improvements i want to make to control line layout. I would like to swap the existing kicker, which cleats in a v-jammer on the bottom kicker block to a led aft to thwart type. Probably with a cascade 8:1. I haven't rigged the boat at this time so have no measurements to get the new one made up to, would anyone know what the spec is?

Also where would be reasonable to attach the turning blocks to - floor (hog) or the plywood just forward of the mast step?

I'd like to lead the cunningham to the thwart too, probably using turning blocks in a similar location.

If there are any miracle sailors on PH I'd be grateful for any tips...
