The leds I got are these:
http://www.superbrightleds.com/cgi-bin/ ... AR#WLED-x4. They are no wider than the 194 bulbs they replaced. The install was as easy as replacing the bulb. I had some difficulty putting in the side marker bulbs so I uses a file to round the sides of the base so they would spread the tabs easier. Some leds are polarized so they will only work when inserted the right way. These include resisters so they wouldn't burn out if inserted backwards.
I used the 32 degree amber in front and red in the rear side marker. For the guages, I used the 90 degree red. The taillights are the red 67-x15
You might have to drop the steering column to get the dash panel out. I managed to carefully wiggle it out without doing that. There is one bulb for each of the small gauges and two in the larger. The clock takes a small bayonet bulb. I'm not sure what size.
I'm not sure how easy it will be to see at night. I'll have to get the car running first.
