In my case it was loose bolts fastening the transmission crossmember to the=
 frame.

I know this has been covered over the years, but would like some input from
folks.  Just redid the rear suspension and driveline for my 67 TR4A IRS.
Installed driveshaft with new u joints, rebuilt diff that was in my TR6 and
did not have clunk in that car, rebuilt original 4A axles with new bearings
seals and u joints, new comp springs, urethane packings, new urethane
bushings on trailing arm, shock link, rebuilt lever shocks.  The original
diff mounts/brackets/pins looked good so didn't weld support panels in.
This is a 72k orig mile car that was owned 45 years by previous owner.  I a=

noise is behind me so has to be in that driveline.  Any thoughts of next
steps for identifying where it is coming from.
Thanks,

Jim,

In my case as well, after checking everything in the rear end and deciding
it must be the differential I discovered one of the transmission mount
bolts was loose (gone actually).  There is a lot that can cause a clunk in
the rear, but don't rule out other possibilities.

Great thoughts by you both on the tranny mount.  I just had the tunnel cover=
 off so kicking myself now for not checking.  May be able to inspect and adj=
ust underneath.  Was thinking it might be a little play in the axle splines s=
ince they are original and or possible wear on wire wheel hub splines or wir=
es themselves.  The wires are the original to car. Have new Dayton=E2=80=99s=
 and hubs to put on soon.
