Chevrolet Corvette Adapters User Manual
Specially designed Chevrolet Corvette adapters (see Figure 1) can be used with the Universal Measuring System’s (UMS) pinchweld stands/adapter tubes or with Universal Anchoring System (UAS) bases. The adapters allow the positive anchoring of Chevrolet Corvettes (1997 - ).
The Corvette anchoring components allow attachment of hold down brackets to oval holes on underside of vehicles rocker panels. The hold down brackets then mount to either UMS basic stands/adapter tubes or to clamp bar tubes inserted in UAS bases.
Instructions
1. Remove plugs from oval holes in bottom of rocker panels.
2. Lift one side of vehicle and position anchoring stands (see options – Figure 1) at front and rear corners of center section.
a. If using UMS pinchweld stands, first lift one side of vehicle and position mounting brackets on main- frame below front and rear corners of vehicle’s cen- ter section. Then slide stands into the brackets but do not secure them in the brackets nor secure the brackets to the mainframe.
b. If using UAS bases, insert UMS adapter tubes, clamp bar tubes, or optional cradle mount tubes and position bases at front and rear corners of center section.
3. Insert head of threaded hold down attachment into oval hole at front corner of center section (see Figure 2) and turn attachment 90 degrees so that head straddles inside of oval hole.
4. Slide oval spacer and oval insert onto threaded end of hold down attachment. (See Figure 3.) Oval insert must fit within oval hole on underside of rocker panel. (See Figure 3 inset.)
NOTE: Early 1997 production models of Chevrolet Corvettes do not require use of oval spacer.
