mounting a dive ladder

[mschrope]

I'm planning to mount a Garelick dive ladder on the transom of my '73 V-20 and am wondering if anybody out there has done this and might have any tips.

I could have sworn I read something here on this topic but can't finding anything now while searching.

Because the transom slants outward, the standard mounting bracket won't work without some serious shimming-- about 1.25 inches as far as I can tell.

If anybody out there has added one of these ladders and has any tips on the best way to do it, please pass them on--- or if this has been covered please point me to the right posts.

thanks
