Nordic Track A2050 Treadmill

Hello,
I just bought a used Nordic Track a2050 treadmill. I removed the tread deck from the frame to get it downstairs. There are three pins to do this. Two on the front and then one on the incline motor. I cannot get the incline motor pin back in. It appears to be to long. Any suggestions on how to get the holes to Aline to get the pin back in?
TIA

Does anyone have any idea what is the best treadmill if someone wants to spend around $1500?

Which company do you recommend how to lose weight in 2 weeks I look at as there are a whole bunch of brands out there?

see treadmills from Sole, Proform, Nordictrack, Life Fitness, and Horizon.
