 Front pillar butt joint can be determined anywhere within shaded area as shown in the figure. The best location for the butt joint is at
position A due to the construction of the vehicle.
 Determine cutting position and record distance from the locating indent. Use this distance when cutting the service part. Cut outer
front pillar over 60 mm (2.36 in) above the inner front pillar cut
position.
 Prepare a cutting jig to make outer pillar easier to cut. Also, this will permit the service part to be accurately cut at the joint position.
 An example of cutting operation using a cutting jig is as per the fol- lowing.
1. Mark cutting lines.
A: Cut position of outer pillar
B: Cut position of inner pillar
2. Align cutting line with notch on jig. Clamp jig to pillar.
3. Cut outer pillar along groove of jig (at position A).
4. Remove jig and cut remaining portions.
5. Cut inner pillar at position B in same manner.

 When a measuring tape is used, check to be su re there is no elongation, twisting or bending.
 Measurements should be taken at the center of the mounting holes.
 An asterisk (*) following the value at the measuring poi nt indicates that the measuring point on the other side
is symmetrically the same value.
 The coordinates of the measurement points are the distances measured from the standard line of ″X ″, ″Y ″
and ″Z ″.
 ″Z ″: Imaginary base line [300 mm (11.81 in) below datum line ( ″0Z ″ at design plan)]
