Looking to fit a vacuum gauge to my Spitfire 1500 and have seen from other sites that the blank off (what seems to be a nut?) on the manifold was the best place to attach a nipple for the gauge?
(sorry for the blurred photos, phones on its way out)
Does anybody know what size thread or where to get this nut? I thought if i could get another one I could drill/tap that and save the original.
Any other suggestions or advice for fitting these vacuum gauges?
