Re: Yarmouth stirrups


The holes in the hatch stops are designed for .0125" diameter wire and # 80 drill bits.
The mounting pins of the sill steps comfortably fit into the holes in the InterMountain underframe. If you need to drill your own holes, use a # 78 drill bit for a tight fit. If you find it too tight use a # 77 drill bit.
