Depending on how nice your willing to keep your gauges, I would place a shop towel or the equivalant over the steering column, remove the screws and pull the cluster out just enough to get your fingers behing the fuel gauge, pull that one first it is the easy one, then move it off to the side either hanging and on the towel or completely out (remember to rememebr the wiring), them get at your tach next, it is the big one so this is where the towel really helps to keep the gauge scratchless, then with the tach out you can reach in fairly easily at the speddometer gauge and remove the speedo cable if you need to or you could just pry as far as it will go and do a reach around
to et at the bulbs your replacing. Install your bulbs and reassemble reverse.. This is the easiest not interfering with complete removal.. basically your buying yourself room to work one gauge at a time..
