[Mg-t] rocker dimensions?

[Carr&Edwards]

The mechanic who rebuilt my TD engine said he found it difficult to get proper
valve clearance adjustment -- the machine shop had resurfaced the rockers, and
he suspects that too much was taken off, as some of the adjustment screws were
at the end of their travel.  Does anyone have--or know of a source
of--dimensional drawings of TD/TF rockers, so we can check those measurements
against mine?

Thanks in advance,
