Tail gate glass is broken . Will one from a 1984 Suburban work ?
Judging from the pic of the yellow blazer I'll assume that it is between a 1973 and a 1979, based on the round headlights, 1980 looks the same but has square lights, the rear glass will work in the blazer, at least I am 99% certain it will. A free easy way to make sure is to go to LMC truck parts web site and compare the part numbers for the suburban and the blazer.
