Bob Bank before the seating

What year did the seats go on the Bob? Trying to work out what year i first watched City i think it was about 3-4 seasons before the seats were put in

I beleive the bob bank [upper] seating was first installed & ready for the start of the 92/93 season.
The first home game of that season was on Aug 15, v Darlington, which ended 0-0 in front of a crowd of 8399. It was also our promotion season under Eddie May, hope this is of help.

Not entirely sure but loved watching the blow up sex doll getting thrown around when everybody congregated under the televsion stand
