I picked up parts from a unfinished 16v swap and am now putting it in my daughters 87 Samurai. I got Trail Tough to put the VSS in the cluster I got with the parts but when I look at them both on the Bench, one cluster (origional) is rounded on the back corners, the one I have with the VSS put in it is more square on the back corners. Is this going to be a problem? the sammy is at a friends house right now and i can't get to it to compare (1 Hour away ) and I am now wondering.... They are the same visually from the front but one has a Tach in it (the one i plan to use) I need help.....Thanks

Come on gang dont leave me hanging LOL ! I am going to be doing this dash as soon as I get the motor in  and would like some constructive input from someone smarter than me on this stuff...... Thanks !

If they both have the 4 bolts that go through the corners, to hold the cluster in the dash, then they will interchange fine.
