The TR4-A's square 'fail-safe' motor mounts are definitely shorter than the
round TR4 style - and that's probably the reason why you have no fan belt space
on your 4A.
I would add big flat washers to new TR4-A mounts, or switch to the taller
round TR4 motor mounts to get the 1/2" space needed for changing belts.. (or
jack
up your motor a little to change belts - not easy to do on the side of the
road)
It is important to know too that the TR4-A 'cone style' rear hood supports
allow deeper travel than the TR4 style 'flat rubber' supports when
'drop-closing' your hood, ie; TR4-A owners risk smacking their hood on the
thermostat
housing - for an ugly dimple - not a problem on TR4s. To remedy this hood
dimpling
problem the factory glued a pad to the underside of the hood right above the
thermostat housing on TR4-As.

Should be enough to pass a fan belt through there.
