1. A vehicle checking mechanism comprising a pair of beams supported in spaced apart and parallel relationship by means of transverse girders welded therebetween, a plurality of spreadable crossing clamps removably attached to said beams, a plurality of upper crossbars spanning said beams, and each received by a pair of said crossing clamps, one on each of said beams, each said crossbar slidably engaged by a mounting bracket, and a reference pointer mounted to each of said mounting brackets. 2. The checking mechanism of claim 1 wherein each of said beams is a hollow box section having an I-beam shape, and said clamps each comprise a pair of U-shaped brackets with each bracket having a flange for engaging an edge of said I-beam, each clamp further including first means for biasing said brackets apart and second means for limiting the separation of said brackets, the U-shape of said brackets defining a passageway through said brackets for one of said crossbars. 3. A vehicle checking mechanism comprising a pair of I-beams, each having flanges defining an I-beam exterior shape, said I-beams supported in spaced apart and parallel relationship by means of transverse girders welded to said I-beams remotely from said flanges, a plurality of crossing clamps removably attached to said flanges, a plurality of crossbars spanning over said I-beams and each received by a pair of said clamps, one clamp on a flange of one I-beam and the other clamp on the flange of the other I-beam, each said crossbar slidably engaged by a mounting bracket and means for mounting a reference pointer on said bracket. 4. The vehicle checking mechanism of claim 3 wherein said I-beams each have an upper flange portion and a lower flange portion, there being a plurality of first clamps mounted to said upper flange portions. 5. The checking mechanism of claim 4, including at least one second clamp attached to the lower flange portion of one of said I-beams. 6. The checking mechanism of claim 5, including an additional second clamp attached to the lower flange portion of the other of said I-beams and including a lower crossbar supported by said second clamp and said additional second clamp. 7. The checking mechanism of claim 6, including a lower mounting bracket slidably affixed to said lower crossbar, a pinch weld clamp, and means affixing said pinch weld clamp to said lower crossbar. 8. In a vehicle checking mechanism, a frame having an I-beam, a crossing clamp engaged to said I-beam, said crossing clamp having window means for receiving a crossbar, and a crossbar passing through said window means and secured to said I-beam by said crossing clamp. 9. In a vehicle checking mechanism, a main frame having spaced apart and parallel I-beams, a plurality of girders extending between and fixedly attached to said I-beams, and centerline guide bars mounted to said girders and extending longitudinally and centrally between said I-beams. 10. In a vehicle checking mechanism according to claim 9 wherein said centerline guide bars define a slot therebetween, and including a measuring device comprising block means adjustably supporting thereon a measuring stick, and said block means having a dowel pin fitted in said slot. 11. A clamp mechanism attachable to a flanged beam for mounting to said flanged beam a transversely disposed crossbar, said clamp mechanism comprising first and second plate members, each said plate member having a window for receiving said crossbar and a lintel above said window, each said plate having a bottom flange spaced from said lintel for hooking said flanged beam, said plate members having fastener attachment means, and a fastener engaging said attachment means. 12. A clamp mechanism as recited in claim 11 wherein said plate members are substantially identical and arranged symmetrically opposite. 13. A clamp mechanism as recited in claim 11 including a compression spring surrounding said fastener. 14. A clamp mechanism as recited in claim 13 wherein said compression spring coacts with said plates to separate the same, and including a threaded means engaging said fastener for opposing said compression spring. 15. A clamp mechanism as recited in claim 11 wherein said attachment means comprises an aperture in each plate aligned to receive said fasteners. 16. In a vehicle checking mechanism, a horizontally disposed main frame comprising spaced apart and parallel I-beams having upper and lower flange portions, a pair of crossing clamp means, one secured to a flange portion of each of said I-beams, and a strut tower frame having a lower crossbar, said crossing clamps having windows receiving said lower crossbar and clamping said lower crossbar to said I-beams, said strut tower frame adjustably supporting a vertically elevated crossbeam, and said crossbeam adjustably supporting pointers. 17. In a vehicle checking mechanism of the type comprising a main frame having parallel I-beams and crossing clamps secured to said I-beams for supporting crossbars on said main frame, a mounting bracket affixed to one of said crossbars for supporting a pointer rod, and an offset pointer clamp engaged to said pointer rod for mounting a pointer which is offset from said pointer rod.
