Accelerator pedal location

[74er]

Hello,
I could use a little assistance. I had a fairly well rusted 911 '74. Over Christmas break I welded in new front suspension pan and floor board. The pedal cluster area was in bad shape. Now it's patched up but I don't have the location to mount the accelerator pedal. The pedal cluster is fairly easy as I'll mark it from it's natural position bolting to the master cylinder. Could someone tell me the location for the accelerator pedal. For example, from the driver's seat, right pedal cluster to floor hole to left hole of accelerator pedal (right to left dimension). And pedal cluster floor hole to accelerator pedal hole (front to back dimension). Unless you can think of an easier or more accurate location. Thanks in advance for anyone who may respond.
