No, I haven't touched anything for the 5.0 swap under or in the dash yet. Would it be easier to just get a 90-93 cluster......crap now that I think about it the cluster will not work because in the 88 its flat and mine is rounded.....hmmm would a 90-93 be a direct go? someone said the speedo will read twice as fast if i leave the 4 banger cluster in there.
