Bristol 400 - access to rear of ignition swx

[Marcus]

A loose contact / bad connection has arisen in the ignition switch and from time to time I lose all electrical contact, normally regained after 'fiddling' with the ignition key in the switch. I really need to examine the rear of the switch unit to either reconnect the wires more securely or effect some other remedy.

So Gentlemen - question - how do I access the rear of the switch? I have removed the two front chrome bezels but the switch 'unit' is held within a metal cradle which seems to be soldered to the metal base plate and clearly was positioned in 1949 and has not moved since! Before I remove the radio - original kit - and try to locate the rear of the switch from below and behind, is there any other simpler means to get at the back of the switch?

Thankyou
