Hi,
I have the quick release on the Moop but one word of caution. It is very easy to catch the spring claws and pull them out of their set position, ie open them up. Once this happens it is a case of getting a new one has the retaining spring force is lost and the pin will just drop out.
I would also mention a possible problem if you are replacing the ribbed rubber boot part number DAM3022. In the past I got a new one from Minispares and having put everything back together and took Moop for a test drive I had a problem.
She would slip out of 2nd, 4th and reverse. I eventually discovered that the new DAM3022 was not to original spec. The rubber was harder (therefore harder to compress) and the boot was about 2 or 3mm longer. This meant that when selecting those gears the shaft was prevented from moving far enough into the gear box to fully select the appropriate gear. I just reverted back to the old boot as it wasn't in too bad a condition, I believe some people have over come the problem by shortening the boot to the correct length even though the rubber is harder so harder to compress.
