am i able to use a guage cluster from a 93 lightning in my 94 f150

 

The dash is exactly the same.

 

yea i know that but the speedo goes to 120 in a lightning and only 90 in a f150 i dont know if thta matters

 

The speedo isn't the problem - it's the airbag. You can't mix '92-93 clusters with '94-96 unless you're prepared to do some rewiring.

But you CAN swap JUST the speedos with no problems. At worst, you'll just have to calibrate the PSOM. While you're in there, you might want to add a low fuel light &/or make the oil pressure gauge actually work.

 

What do you mean by the oil pressure guage not working?

i always wondered why it doesn't move around like my old gm's did. i just decided not to mess with it since everything seems to run fine.
