PPG Sawdust is the closest matching paint I've found, but it's not an exact match. Please contact me if you've had the paint matched.
I believe Ibanez uses metric screws, however, Imperial sizes are close enough to generally be acceptable replacements.

Most standard P pickups (Seymour Duncan Quarter Pound SPB-3, EMG, etc.) should be a drop-in replacement.
Epic Custom Shop 92mm length J pickups require a small amount of sanding and new screw holes.
Gotoh VK1-18, VK1-19 knobs have 6mm smooth (no splines) shaft holes with a set screw and will fit the factory pot shaft.
Gotoh GB350 tuning machines are a drop-in replacement if the Gotoh ferrules (14mm outer diameter) are placed into the TMB factory ferrules, (14mm inner diameter) and a new screw mounting hole is drilled.
Hipshot Licensed 3/8" Ultralite Bass Tuning Machines have a shaft diameter of 13.75mm. Shimming around the shaft is required to prevent a sloppy fit. Wrapping about 9 inches of tape around the shaft will shim it to 14mm and they can be placed into the factory ferrules. However, the shaft will only enter the ferrule to a depth of 1mm, which will likely be adequate, but does not make me confident. As an alternative, a plastic or nylon bushing, sleeve bearing or spacer measuring 9/16" I.D. x 11/16" O.D. may be placed between the tuner shaft and the headstock hole. Unfortunately, I've had a difficult time finding a suitable bushing. I used Redline (Trailer Parts Pro) model SP05-020 (or SP05-040) bushings trimmed to a length of 8.5mm. The bushing required a few inches of tape around the outside to make a snug fit into the headstock hole. The tuner shaft required a few inches of tape to make a snug fit in the bushing. A new screw mounting hole is required. Although these tuners can be made to fit, I personally do not recommend using them in the TMBs. The Gotoh GB350 tuning machines offer a much easier fit. Please contact me if you have a good solution.
Hipshot USA 1/2" Ultralite Bass Tuning Machines require a 17mm or 17.5mm hole and might be a drop-in replacement with a new screw mounting hole and possibly some tape shimming around the shaft. (Unverified)
Hipshot USA 3/8" Ultralite Bass Tuning Machines require a 14mm hole and may be a drop-in replacement with possible shimming and with a new screw mounting hole. (Unverified)
Jack plate model JP-CST-C (chrome), JP-CST-B (black) are drop-in replacements.

Some pots have imperial or standard sized threaded shafts with a diameter of about 3/8" (0.38"), e.g. CTS, but the TMB pickguard pot holes are only 0.35" (8.9mm) diameter. Metric pots with a threaded shaft diameter of 0.3" (7.7mm) are drop in replacements. Credit: ThumpingJack, talkbass.com
