140 speedo install wtf
ok so i bought a 87-89 140mph speedo for $50 off this kid i kno from the car meets around here. how easy is this to do? it doesnt look that hard but i could be wrong. is there n e thing i shood look out for while im doin it?
ive seen a pic somewhere that shows how the dash comes apart but idk where to find that.
any advice/pictures/links to other threads would be helpful (tried the search thing but i cant seem to find n e thing)
thanx!

RE: 140 speedo install
It is a straight forward swap, there are 4 screws to take out for the bezel over the speedo, the steering column cover and I think 4 more screws for the speedo as well. The light switch, hazard switch and defrost can be a bit tricky. The toughest part for me to disconnect was the speedo cable. The connections for the wires to the other guages are easy to disconnect as well.

wellthat cable looks pretty secure on the tranny but should i undo it and try re stabing it?
but the little square part in the cable still turns.... clockwise
