I want to fit a quick rack to my MK Indy but looking at the MK site it seems they modify the Sierra rack. Will a stock quick rack fit the Indy? If so - any suggestions on where to buy one?

Nope, the rack needs shortening. The one you have now is (in all likelihood) a shortened sierra rack. In a rash of excitement over planning I bought the internals recently to have a go at modding my existing rack but after reading up on the job it's not one for the faint hearted. Just buy one from MK.

OK. Thanks for that, I'll buy direct from MK.
