Two goals in a minute, the first from County’s Paul Turnbull and then one from away specialist Deane Smalley brought to life what up to then had been a largely turgid encounter.
The draw means it’s 9 without defeat for Spireites. Stockport’s home record shows just 1 win in 24 attempts.
With Jack Lester, Gregor Robertson and previously ever-present Simon Ford out with minor niggles and Derek Niven switched to the bench, John Sheridan brought in Javan Vidal, Ian Morris, Deane Smalley and, making his return to the side after re-joining Spireites from Peterborough, Scott Griffiths.
Rock-bottom County had Ishmel Demontagnac, who had a good loan spell at Saltergate last season, up front. Striker Anthony Elding had pulled up lame in the warm up and had to be replaced by Jordan Rose.
It took 12 minutes for the leaders to carve out an opening, Drew Talbot robbing Rose but Smalley was unable to adequately control the ball in.
The game was beyond the half hour mark before County forged any sort of chance, and from the game’s first corner, the opening ended with a shove by Rose and Tommy Lee remained untroubled.
Matt Glennon had to react quickly to gather a Daniel O’Donnell slice towards his own goal following a Talbot cross and a Talbot left footer that bounced unevenly was the only shot on target before the break, though Morris put a 25 yarder just wide.
Morris drove a long range free kick high and wide then Rose headed over following a Demontagnac free kick as the game began to open out.
Craig Davies, who had a power-blaster blocked, flicked on a Vidal free kick but Dwayne Mattis was just unable to connect six yards out and Lee had to get down to gather a Demontagnac shot on the turn.
Davies came within a whisker, thumping a 25 yard free kick against the frame of the goal, County were lucky to escape as the rebound pin-balled around for a while.
However it was the hosts that dramatically snatched the lead with Turnbull volleying in from close range from what looked a suspiciously offside position, though the advantage lasted just 60 seconds, Smalley heading home from close range from an inch perfect Danny Whitaker cross.
Lee caught a decent O’Donnell header and Morris hit high as both sides sought a winner, County winning a brace of corners right on 90, O’Donnell firing the second over from six yards before Talbot left-footed just wide to bring the chances to a halt.
