Thanks for all the kind words!

I'm not sure if the original poster was inquiring about hood or door hinges.

On the door hinges I have a couple points to add...
my kits have pins & bushings for the top hinge.
For the lowers, an oversized pin to allow the hinge to be reamed oversize. (Reamers available as well.)
Also included are new "S" springs which you won't find at a local parts store that I'm aware of.

Below is a picture of a pin & wavy washer that I'll be offering separately soon as well....
this is for replacing the detent roller pins & wavy washers. On more severely worn out hinges, often the pin becomes worn and allows the roller to move around. This will cause the S-spring to ride up against the pin head and messes up the detent feature. (These are what hold the door in the 2 different open positions and keeps it from swinging back closed.)
Also, the wavy washer sometimes is corroded, missing or failing, which leaves the roller loose.

I don't do a ton of door hinge rebuilds because as mentioned, it is quite easy and hence the pin kit I sell. For door hinges where the detent rollers are in poor shape, I'm getting sets to do.
For repairing these, the new pins have to be spot welded in place.
