Replacement pins for 68 rallye dash main circular electrical connector?

If you just want a few, probably someone on this site has them. Then you have to mount them firmly. I've got an old board and the pins are pretty loose. The whole circuit board with the pins has been reproduced. Try Classic Industries part #MA118509. Cost is $125.
