+4 jacking question

[David Stillinger <dstillin@qualcomm.com>]

Could someone with a 60's +4 tell me which set of floorboards the access
hole is located for the jacking points? My floorboards were replaced years
ago and I never put the holes in. I'm redoing the car now, have an original
jack, and want to make the cutouts. Are they located in front of the
chassis cross member (toward the engine), or behind? What shape are they,
circular or D shaped?

Thanks for any help
