Had some problems with my other manifold so I got the minispares "torquemaster" manifold to use instead and I cannot tighten the innter two nuts, access is fouled by the manifold, either with the short or long brass nuts!
The socket fouls against the manifold - using a shot nut and a "wobble" extension I could start to tighten it but it also locked the socket itself against the manifold.
This seems like a design oversight on something they claim to sell 900+ of a year. The other manifold I had was at least easy to get off and on.
Also I would like to add that the stud holes for the carb were not straight at all and I had to waller out my spacer a bunch to get it to fit. This is not the first time I've had quality problems with a minispares item recently. I'm glad they make just about everything but in general I don't mind paying more if it means the quality is there, I'd rather not spend my time fettling to make new parts fit!
