aperture 82 in mounting surface 66 of the snow plow blade 32 likewise one of the bolts 132 is threaded consecutively through the aperture 216 in the bottom 210 of the recess 198 through the corresponding coaxially aligned aperture 176 in the bottom 172 of each recess 158 of the overlapping portion 234 of the outer section 92 and then through the corresponding coaxially aligned aperture 82 in mounting surface 66 of the snow plow blade 32 the center section 94 is directly secured to the portion 228 of the top member 44 of the straight snow plow blade 32 by threading one of the bolts 132 through the aperture 216 in the bottom 210 of the recess 198 and then through the corresponding coaxially aligned aperture 82 in mounting surface 66 of the snow plow blade 32 as best illustrated in fig8 and 9 the deflector 30 is adjustable to straight snow plow blades of different widths 38 for example the snow plow blade 32 shown in fig8 and 9 is shorter than the blade shown in fig5 and as such the end 186 center section 94 overlaps a larger portion 300 of the of the outer section 90 so that four recesses 198 thereon seat within the four corresponding and aligned recesses 112 on the outer section 90 likewise the end 188 of the center section 94 overlaps a larger portion 302 of the outer section 92 so that four recesses 198 thereon seat within the four corresponding and aligned recesses 158 on the outer section 92 it is preferable that each end 186 and 188 of the center section 94 overlap the same number of recesses on the.
