Measuring apparatus for use in vehicle collision repair work. The measuring apparatus comprises first and second telescopic extension members each having a first end for affixation, respectively, at first and second reference points. A cross-member is connectible between the second ends of the extension members. Indicator means are provided on each extension member for indicating displacement between the extension member first and second ends. Alignment means are also provided for aligning the extension member second ends on opposite sides of the vehicle center line and at equal distances from that center line. Third and fourth indicator means are also provided for indicating, respectively, the vertical height of third and fourth reference points above a reference line defined by the extension member second ends. The third and fourth indicator means also indicate, respectively, horizontal displacement of the third and fourth reference points from the vehicle center line. The measuring apparatus may be quickly connected to most collision damaged vehicles despite the presence of obstructions which frequently interfere with conventional measuring apparatus. The collision repairman may then, without moving away from the front of the vehicle, align the measuring system with respect to the damaged vehicle, lock it into position and obtain measurements indicative of the extent of collision damage to the vehicle.

Measuring apparatus as defined in claim 4, further comprising third indicator means for indicating the height of a third reference point above said second reference line. 6. Measuring apparatus as defined in claim 5, said third indicator means for further indicating horizontal displacement between said bisector and said third reference point. 7. Measuring apparatus as defined in claim 1, 3 or 4, wherein said first and second extension members each comprise a sleeve and an insert slideably retractable within said sleeve and slideably extendible therefrom. 8. Measuring apparatus as defined in claim 1, 3 or 4, wherein said first and second extension members each comprise a sleeve and an insert slideably retractable within said sleeve and slideably extendible therefrom, and further comprising locking means for locking said inserts with respect to said sleeves. 9. Measuring apparatus as defined in claim 1, 3 or 4, wherein: (a) said first indicator means comprises a first measuring tape having a first end fixed with respect to said first end of said first extension member and having a second end fixed with respect to said second end of said first extension member; and, (b) said second indicator means comprises a second measuring tape having a first end fixed with respect to said first end of said second extension member and having a second end fixed with respect to said second end of said second extension member; whereby extension or retraction of said extension member second ends with respect to said extension member first ends correspondingly extends or retracts said measuring tapes, thereby indicating displacement between said extension member first and second ends. 10. Measuring apparatus as defined in claim 4, wherein said alignment means comprises: (a) a first alignment member fixed to said second end of said first extension member to project from said first extension member at a selected angle with respect to said first extension member; and, (b) a second alignment member equal in length to said first alignment member, said second alignment member fixed to said second end of said second extension member to project from said second extension member at an angle with respect to said second extension member equal to said selected angle; whereby end-to-end positioning of said alignment members locates said bisector, aligns said second reference line parallel to said first reference line and aligns said extension member second ends at equal distances on opposite sides of said bisector. 11. Measuring apparatus as defined in claim 5, wherein said third indicator means comprises an indicator member on said cross-member and vertically, slideably extendible with respect to said cross-member. 12. Measuring apparatus as defined in claim 11, wherein said third indicator means is horizontally slideably mounted on said cross-member, and further comprising indicator means on said cross-member for indicating horizontal displacement of said indicator member along said cross-member. 13. Measuring apparatus as defined in claim 2, wherein said alignment means comprises first and second alignment members fixed, respectively, to said extension member second ends to project from said extension members at equal angles with respect thereto. 14.
