Triumph Repair: 1975, 1500 Fuses, amp fuses, fuse box

Question
I have a 1975 Spit 1500 and the fuses under the hood located in the square, 3 fuse box on the firewall are broken/blown. Currently, the car runs great, but my brake lights, running/headlights and the tach & gauges (expect the speedo) are inoperable.
Do you know the correct British/US fuse "conversion?
And which spot they go? Thanks.

Answer
Hi Todd,
The Lucas fuse with the wire in it and paper are the same as US fuses. Most came with 35 amp fuses in all positions. The wiring can handle a little higher amp if you blow a fuse when operating everything at once. This tube type fuse is available at any auto parts store just get the correct length.
