Your best bet is to pick up the Yeah racing motor mount. Then you can mesh with ease.

Also with the TATT-034 Anti-Roll Bar Mounts I could not get the screws in the the Tub Chassis. The holes in the bracket seem to be 0.5mm to far outboard on eighter side. So elongated holes where needed.
With the Lower Arm Mounts TATT-028 and TATT-029 I could not push them all the way in X till they sit against the Tub Chassis. The tab for the bottow Z-screw seem to be slightly wider then the humps on the chassis below the differentials. So I have to shave some material eighter off the chassis or the aluminum mount.
I get the impression that somebody at Yeah Racing does not know how to use a Caliper. 😣
(Not to mention the Long Span Suspension Kit for the GF-01 / WR-02, making it fit was a nightmare.)

I also had the fitment issue with the Yeah Racing motor mount, but it only required a very minimal amount of massaging to make it work. I did buy the PSM mount, but haven't tried it yet. It looks to have a much larger motor positioning range.

Looks the same to me, just different color.

I'm hoping I'm the only one that is having a problem with this. But I've noticed that in the last two Yeah racing motor mounts I bought - the radius of the arc opposite the pivot point that the motor screw goes through is too small - The result is that the motor screw hole winks in the slot - forcing the locking screw to cross thread on an angle into the motor - NOT GOOD - fortunately I have access to machines to fix. I'm not sure if the issue is with the Brushless (Fantom) motors I use? Or a bad batch of motor mounts/. Buyers beware!

- the center opening is a bit more oblong, looks like they managed an extra degree or two at each end...Either way, its too bad Tamiya hasn't made an adjustable piece like this.
The fixed unit can work, but you need to "trial-and-error" to figure out which combination of 64p spur and pinion works for the various hole pairs.

Ah, That's clearer, I see it now - the center opening is a bit more oblong, looks like they managed an extra degree or two at each end...Either way, its too bad Tamiya hasn't made an adjustable piece like this.The fixed unit can work, but you need to "trial-and-error" to figure out which combination of 64p spur and pinion works for the various hole pairs.

To match the final gear ration:
Mod 6 - 64/27 = 2.51
48p - 78/31 = 2.51
