RCBS neck sizing bushing dimensions

[beanns2]

Im wondering if any one could supply me with the dimensions for a neck sizing bushing for a RCBS Gold Medal Full length bushing sizing die in 7mm08. So I would need OD and length. I bought the die with out knowing it did not include a bushing. Just need to make one dummy round for my gunsmith to check throat depth on my new build. If anyone could supply me that info tonight that would be great.

Thanks,
Beans
