Way dumb body mount question

[1976Blazer76]

Got my poly body mount kit the other day, and I'm having a little issue. Well, the very back mount on my blazer is that weird looking flat rectangle one, not round cylinders like the rest. Why didn't my mount kit come with one like that? Also, that rear mount is stuck on the frame, do I just scrape it off? Or, does the new mount kit come with replacements that don't look the same as the stock ones? Noob question I know, but it had to be asked.

aal the replacement mounts are round. it doesn't make a difference. the hardest part is dropping your gas tank to get at the back bolts. that and puling out your interior.

Allright, thats what i was thinking thanks. Well good thing I'm doing the frame off, all the tank dropping and no interior is allready done..
