When installing new door pins on a 1981 corvette,.under the head of the pin is a spline when you tap the pin in it gets to the spline and stops the pin from seating in all the way.i tried but there was no way that pin was going in any farther. what am i doing wrong? or is it possible they gave me the wrong replacements. would really appreciate some answers thank you very much

1. Place masking tape on the inside edges of the door, on both the inside and outside of the door. 2. Remove the door spring by using a door spring removal tool. Insert the tool into the door spring, turn the knob with a screwdriver to compress the spring, then pull out the tool. 3. Set a 5-gallon bucket under the door. This will help support the weight of the door. 4.Place a nail punch under the hinge pin, and strike it with a hammer. Repeat this until the hinge pin begins to come out of the hinge. 5.Place the end of a flat-head screwdriver under the top of the hinge pin, then strike the screwdriver with the hammer to force the hinge pin out of the hinge. 6. Place the bushing on top of the new door hinge pin, and tap it into place with the hammer. 7. Insert the new hinge pin into the hinge. Tap on the hinge pin with the hammer and nail punch to force the pin into the hinge. 8. Insert the hinge spring back into the door, and release the tension on the spring removal tool. 9. Spray the door hinge with a lubricating spray or apply grease.

I know there are a few directions but it is fairly easy to do. If you have access to an air hammer and a compressor you can use this in place of a manual hammer to make the process a bit easier.

Hope this helps.
