narrow case gear selector drum

I am assembling a 350 n/c bottom end for my racer from a collection of parts.. The 5 speed selector drum I have I find is too long by about 5mm (so the cases won't close). looking at parts books I find n/c and wide case engines have diferent part numbers for their selector drums, so presumbly they are different. looks like I've got a wide case drum..
Can anyone confirm this

Yes, the widecase selector drum is wider than narrowcase.

I can provide you with a NC 5 speed shift drum. Where would it ship to?

Hi Phil,
I’m in California, some ways from Derbyshire, but I have shipped parts to the UK (Ian with the 175TS in this group) which seemed to have went well. If you wish to proceed, please send a PM and I will let you know what I can offer.
