measure the side to side width of the wheels mounted on the axle(the absolute widest point including any tire hangover). than figure out how high its gonna go into the wheel well and measure the side to side where it needs to travel to in the wheel wells/quarters. than just just shorten it to fit in between. for example my wheels installed in the axle were 66" wide and the quarter curved in to 63" where they would finally rest laid out. so i took two inches off each side for a total width of 62 which gave me enough room to fit my tubs against the quarters. shortening your axle an extra 1/2" or so on each side isnt a bad idea just to be sure everything is gonna fit perfect and give you more room for wider widths in the future if necessary. i did it this way on my cutlass and got it perfect. also sometimes depending on the style of the axle they cant machine them down. mine were the this way so i just bought moser axles (super beef cake and any length you need) they ran me 360 for both sides. C-clips suck (can fail with very bad results) so if you end up having to switch out axles also have them weld a new ends on the axle to eliminate the c-clips (not very expensive). i paid 1050 for new moser axles,ford 9 inch style axle ends (eliminates c-clips and has supper beefy bearings), wilwood four piston rear discs, and all the labor. also if the place your getting your axle done at offers a c-clip eliminator kit dont get it because they are infamous for leaking on frequently driven vehicle (this is why i did the ford axle ends instead) hope any of that helps.
