Xj6 1975 3.4 cam shafts ,

Not to nit pick, but there’s something unusual about your dash - the Mark 2 was black vinyl, the S and 420 had veneer, but it was burl, not sapwood. And your gauges aren’t correct, or aligned neatly, your clock is missing, and the instrument panel screws have the wrong head.

lol , that’s because the dash is on a test bed , just knocked up to make sure all is fine , before I install the engine , with luck over the winter !
