Nice work there Rod. That big tank was a mess.
On the pre-'73 T150 and T100 tanks I have, the standard trim fixing hole is wa-aa-ay too big for the clip. arn The clip's thread is only 4BA; on my T150, I fitted a 1/8" ID, 1/4" OD stainless washer from Dave 'n' Richard Middleton under the nut, or the nut virtually pulls through the hole.what diameter hole should the small hole for trim fixing clip be ? - just put a pilot hole in for now
