I have always liked the dash in the 70's trucks better.
Will it fit and what is involved with a swap?
Heater box issues?

 

yes 100% interchangable. (bud of mine put 80's dash in 70's truck) not too hard but I cant recall if he might had to pull out windshield or not to do it. he was scratch building a beater truck from the auction.original dash was hacked to death so he got 80's dash. did not take him long to swap out. If you can do it one way, you can do it the other.

 

There's a thought the 80's dash is U L G Y !

 

to each there own. i kind of like the 80's dash.
