midget question

I have a 1975 midget that I am in the process of putting an engine from a 1978 midget in. What differences will I have to deal with besides the electronic ingnition. Should I change the dash and wirring harness? The 1978 is in much better shape than the 1975. Thanks for any info.

No Need to do anything else unless you are putting in a 1500 instead of the 1275. Then consider changing out the fuel pump (and tranny of course). Make sure your electrical system is grounded the same. Some units in 75' were still negative grounded.

Thanks for the response. I am putting in another 1500 since that was in the car.
