I've been looking to replace my front arms on my TOMSE with arms that have sway bay provisions.

The new arms, OT201HB, look correct but they may be longer than my original OT69.
Any help in measuring the front arms of a new Optima Mid would be appreciated.






There seem to be 4 variations, OT201, OT201B, OT201H and the OT 201HB.
My front dog bones measure 68mm overall, 62.3mm pin to pin. New Optima Mid bones (OT 272) look to be 64.7.

Still looking for help with this? I have a rere I am bust open to check out

Don't open the kit if you weren't going to open it to build or inspect.
But if you were going to open it anyways I am still very curious as to this dimension.
I will get them to use on my TOMSE rebuild if they are the same size but something tells me that they are wider.

Thanks
Chuck

Unless I am mistaken, the only difference between the numbers without H and with H are that the latter are the Hard arms.

The "B" seems to stand for a second version of the parts with a price increase to compensate for the current material supply crisis, if other Kyosho rere parts are anything to go by.

The longer length of the dog bones might be to fix the originals being slightly short and popping out of the outdrives at certain extreme angles...
