Folks: your advice sought - I've just received an insurance claim replacement 'scope for my horrifically-wounded C11.

My original C11 was Fastar-ready.

The replacement C11 is not (probably older stock).

Is it possible to transplant the Fastar fitting from one C11 to the other, without buggering around with moving secondary mirror or knackering collimation (original C11 Fastar has Bob's Knobs installed, which help)?
