Can someone please help how to mount the trunnion shock into frame?

Frame itself has ~ 58.4mm between bearings.
But trunnion inner bolt shims came with the frame is 2.4mm wide. 58.4 - 2x2.4 => 53.6mm, but trunnion shock is 54mm => it does not fit between the shims

The part of the frame is not flexible at all to compensate the 0.4mm

Could someone recommend fork? Unfortunately I am far away from MTB to understand anything about it

RS/FOX. RS is cheaper, and I do not know if fox much better because it has 2x price
If RS, Do I need remote (for XC races)? I heard that Deluxe is fine for climbing without lock, but sidluxe is more DC shock that is why remote is necessary for uphill. Probably RT3 can solve it? What the f* is MegNeg? About SIDLuxe - not clear if trunnion has remote


My short list:

RockShox Deluxe RT3 Debon Air 165x42.5mm   268.9
RockShox SIDLuxe Ultimate RL Solo Air   285.71
RockShox Deluxe Ultimate RCT   286.9811939
Fox Suspension Float DPS Factory 3Pos-Adj SV   488.49
Fox Racing Shox Float DPS EVOL SV 3POS Factory Trunnion Rear Shock - 2022 Model   528.57
Fox Float DPS Kashima Factory Series 3Pos-Adj Trunnion Evol SV   569.5218394

Thank you,

If I summarize all the basic math:

1) most of the droppers does not have offset => saddle moves forward even a bit more
2) The main diff for the frame makes seat-angle and Saddle-BB distance is ~8cm diff from old geometry => it is the ~same diff like Road and TT bike saddle

^^^ all the things are the ~same on M and L frames, so the only important diff is Reach

I do not care about stack in terms of saddle-height - it is just 1.5cm diff. But in terms of handle-bar height, sometimes lower stack helps to lower the handlebar without slam it down too much.

And looks like the main diff is really only top-tube length, which is 61 or 64cm, and to compensate your saddle-handlebar distance all you need is stem which is 3cm longer or shorter. So, frame M+10cm stem = L+7cm stem or M+6cm = L+3cm. Looks simple - all I need is to decide stem length.

Small point that L frame adds 0.5cm _back_ to the saddle => to hold the same top-tube you should substract the 0.5cm from stem too.

If I go M => it is not very aggressive position compared to L, I can compensate it with stem, but, probably it is not idea on descend. and 3cm shorter wheelbase, which, probably makes it a bit more nimble, which is a plus for the long bike
If I go L => stem is shorter, and body position is a bit lower too, the only negative thing that stack increased, which prevents you from going lower with handlebar

Is it still alive manufacturer? I have sent request few days ago and no response.
