Question about DIY surf/wake rack

[TL7]

I've tried the search function, but most of ed's posts that have the info have been deleted.

I'm trying to verify (boat is not here currently) that the racks listed will replace the stock Moomba forks using the existing clamp/mount. These are the forks only; I believe Ed did this and it matches up perfectly, but wanted to verify before I ordered them. Otherwise I'll have to wait until I can make it to the storage to measure.
