Great news Redee. The tricky to bend hard lines between the caliper and flex line are available through Toyota for $16ea! The rest is obsolete.
I opened up an ebay $3 impulse purchase last night to test it. Cheap voltmeter, the 8-bit display looks period correct for the 1980’s, but the blue does not fit. Shoulda bought green light. This Might end up in Redee’s dash somewhere.
