New cap should be 7psi. Be careful - there are 4psi ones around.

Don't know about "AE Payen".
The first TR4 was built on Jul 18, '61. TR3/3A production stopped in Autumn
'61. Shortly after, the US dealers asked for more sidescreen cars. Triumph
complied and in March '62 started building TR3B's. The first 530 TR3B's
(TSF1- TSF530L) were basically TR3A's. The second batch (TCF1-TCF2804) of
TR3B cars used TR4 geearboxes and engine. TR3B's stopped being built sometime
in Dec '62. so there were several months (Jul'61 - autumn '61) when both
TR3A's and TR4's were being built simultaneously and about 9 months (Mar'62 -
Dec '62) when TR3B's and TR4's were being built together. I've seen photos of
the assembly with both types of cars on it.

The TR4 suspension is not exactly the same as the TR3. The trunnions are
different and there are some other very minor differences (seals). If your
frame has an "X" type bracing with a sort of box in the middle of the "X" then
it is a TR4 frame. If it looks like a "bell" connected to an "A" with a
crosspiece (running parallel to the bumpers) at the connection, then it is a
TR4A frame. Clear or not?

Aahh. Yes - money. Good luck. Hope this helps. Cheers.
