seeing as rallye dashes never came in scamps to begin with you would need to find a complete dash w/ ralleye gauges and frame to use in the scamp. if you want a rallye dash in the scamp you will have to take the complete dash frame out you have now and basically start over with a rallye dash frame to make it work. then you will need to get the correct wireing harness to connect the new gauges in the dash. what you are talking about doing is all possible , but it is a major undertaking that is going to take a lot of time and money. it was said earlier that there are not many scamps out there and this is true. you would be a stand out in a crowd if you kept you car as a scamp, and miles ahead it time and money spent as well. add some scoops and drop a 340 in it and let it go!
