Gooseneck sheave assembly for reefing lines?

[memelet]

My boom currently has the reefing lines going to a winch on the boom. The placement of the winch is/was way forward, requiring me to move outside the mast pulpits to use the winch (just another WTF).

So I would like move the winch to the base of the mast under the gooseneck. The problem is that I need a sheave assembly with cams built that can be bolted or welded on the boom. I would prefer if it could be bolted on as I've (stupidly) already had the boom painted.

Does anybody know of any pre-built assemblies, as the cost to fabricate seems to a bit steep? The yard I'm working recommended that I look for a prebuilt if possible.

BTW, are there any pro/cons to placing the reefing winch at the mast base vs on the boom? (Assuming the boom winch is moved further towards the gooseneck, that is).

thanks!

check out www.rigrite.com for cast gooseneck assemblies. Selden makes some too, as do others.
what rig do you have?

I think its a Hall Spars on a Passport 42. You saw it when you packed for shipment to SF.

I've looked on rigright but didn't see anything that didn't seem to be designed specifically for one of the booms they sell.
