OK, some pics.
OFR from 169.00
shipping about 10.00
Rock solid, beat the hell out of it and it still stays in tune.... Priceless
37mm block came with the OFR, fits fine, I think the 42 would have fit also
Make sure it says "Made in Germany"
The OFR studs screwed right into the existing inserts, lined up perfectly
The right side is close but it doesn't hit in any way
Small gap on left side but strings line up perfectly
Finally set up, thank god, quite the pain
End product, I'm loving the "FRED" in the bridge too
I've heard that the tolerances are not really that tight in the manufacturing process but in my particular guitar, the studs were spaced absolutely perfect and the cavity accomodated the OFR nicely. All in all, a pretty easy upgrade. Hope this helps anyone considering this.
