updated mine in the 52 to Omega gauges. after 200 miles i like them. got mine from speedway.cost w/ shipping was $474. best part for me was the electric speedo. i ran for years without a speedo and it is nice to have it back. btw i run a ford 302 and c4 trans. in my gmc(yea,I KNOW), no problems with the hookup.
