if it's the left side that's bad, save the cost of a pedal and trouble, get a crank or arm. If it's the right, OK I see that now, it IS the right. Call around for a HeliCoil, or "thread repair kit" of another brand, cost 12 to 15 in that size.Make sure the tread on the pedal is good. HeliCoils work well but there IS another brand..S/S .Porche uses thread inserts through-out the engines, they work. You find the kit, PM me,I'll advise. The arm 'll be a bear to find, as far as swappin' the crank-out, perhaps but more work and $$$
