Couple of Minor JT-6 to OFR Q's

[SausageofPower]

I've had a Model 4 for ages, and I love the guitar to death. I've kept it in excellent shape, but like most of you I'm interested in swapping out the JT-6 pot-metal floating trem for the genuine OFR.

I've read other threads, but I just want to ask a couple of questions:

1. Since I have a non-recessed bridge, I would want a 42mm sustain block, right? I'm looking at throwing a tungsten sustain on there and want to make sure I order the right size.

2. The pivot posts for the JT-6 are compatible with the OFR I know, but is the threading the same on the new posts that will come with the OFR when I order? For the sake of "everything shiny and new" porn I wouldn't mind swapping them out (they appear to come preloaded into bushings, but I'm assuming I could just unscrew them and put them on my Model 4, assuming the threading is the same), even though it's an extremely minor piece of hardware.

I think I'm up to date with everything else on this swap. Locking nut stays the same (though, if anyone can point to new parts/screws for it, I'd appreciate it as mine are a little beat up and I wouldn't mind freshening it up a bit), etc. Any other tips? I plan on ordering things up and doing it this next month as my birthday present to myself. Thanks!

1) yes, 42mm

2) no, OFR posts have much finer threads than the JT-6 posts & bushings. If you want new posts, Dave at fretsonthenet.com makes posts that will fit your JT-6 bushings and are more compatible with the OFR knife edges.

I'm assuming the locking nut is the behind-the-nut string lock. If the top 3 lock down screws uses a flathead screw, it's made of the same soft metal the JT-6 is made of. In that case, I advise replacing it w a Kahler-made one...better materials.

See this recent thread for reference:

Great, thanks for the replies. In the case of the string lock, I was hoping there was a better quality part (I've noticed the general softness of the metal it was made of when I took the guitar apart to detail it). I'd need the Kahler 5513 Std, right? Thanks again.

I'm not hip with Kahler id numbers, but it you want the kind that has the cutout on top for the truss rod access. Here are 2 ebay auctions w the kind I'm talking about. These things also come in varying widths, but that's less of an issue since the neck has its own nut. BTW, I don't know and can't tell if these 2 lspecific ocks below are the same or not.
