Interior Bulbs

I am trying to change the bulbs in the interior. I got 2 194 bulbs and 8 74.When I took off the fron cover, I could see the bulb for the fan speed. I took it out and tried replacing it with a 74. Doesn’t fit. The one I have is fatter and taller, and the base it shorter and wider. I am using conventional bulbs, not LEDs. Do I only need 194s and 74s, or is there another size than i was supposed to get?

Also, when i tried taking out the guage cluster, it would only move about an inch, and that was it. I couldn’t reach around to disconnect the speedo cable. Where exactly does the cable pass through the firewall, so i can get some slack? Or Is there another way to disconnect it.

speedo cable… hooked up to vss (vehicle speed sensor) is on the top of the tranny. will have a lil fancy clip ring thingy on it, dont’ lose it. once u take out the pin, gently pull the cable out of the vss. then that should give u some more slack at the gauge cluster. make sure the other connectors are unhooked too.
