Jib cleats

[wroundey]

I plan to do some work on my jib cleats this fall and was wondering if there is good backing material under the cockpit coaming? My blocks are currently mounted there but I have the opportunity to add some tracks and sliding cars but need to know if there is backing for my screws

When I removed the jib car tracks to repair cracks in the coaming glass and gelcoat underneath them I found that the screws went into what looks to be plywood under the glass. ('86 16II) Also, I was surprised how much the tracks sprang back to near straight once removed and how much they had to be pulled back into a curve as I re-screwed them.
