Looking for a good pic that shows the orientation of the sender studs.

I am wanting to try to Retro fit my tank to accept a sending unit. Pacific Oil cooler did not want to tackle it, but will clean it all out again when done.

I have not been able to find the pic I need on the net. Jason at Paragon, suggested I try to see what you guys have in your pic archives or have a tank you can post a pic of.

Also, How are the studs attached to the tank ? , see any reason I could not use nutserts to mount the studs, or is it too tight a fit on the inside to get the sender in ?, better ideas ?

Thanks
