replace oil pressure sender - uh ? ...how ?

So after getting a shiny set of three mechanical gauges, getting a pair (big 'n' small ) replacement oil senders and a T-fitting, ordering copper capillary pipe to replace the brittle plastic tube, deciding where the binnacle will sit, I got my tools and headed off today to install said set of gauges.
Thankfully, I started at the sharp end and didn't start feeding stuff through the firewall ...
(just so you know, sender sits at the back of the engine in my Challenger, against the firewall)
God only knows how the sender was put in, but I'm guessing it was while the engine was out, which would explain the spray over from the red paint the block is coated in - after removing air filter to gain access, its made no bloody diff' !
Do I need to remove the dizzy ? the ONLY aspect I have on it is from above, and I'm guessing (again) that the hex nut I need purchase on is below the "bell" - there seems to be a "stepped" ring around it but I'm not sure that it would mate with a socket.
To be fair, considering calling the whole thing off or taking it to someone who can ......
Currently, the idiot light doesn't function and although the levels are good and she doesn't overheat, I don't want to tempt fate.
Am I stupid to think there MUST be another port available to plumb into - if so, I'll just disconnect the old sender and leave as is ?
Any help appreciated, if you're close by and fancy a crack @ it, I'll buy the beer/wine/cider ......

dizzy out will help, mark the position and ensure it goes back in same place

wide socket will go over oil sender

maybe a smidgen of carefully applied heat would help, careful of wires etc

it a fine thread so shouldn't be too hard

more a case of getting enough purchase on it

That's an Oil Pressure Switch not Oil Temp.

oooo I read that again, isn't that odd that when you think you've read one thing and it's actually different.

yes garp that's the pressure.but I think that's what you meant

if you want oil temp then you can get a sandwich plate that goes near the oil filter take off with a temp feed.

Yup - I meant pressure switch, not temp...

I can come up to Lyneham Sunday if that suits - be great to meet someone else with a similar car as I have other niggles under the bonnet I'd like explained ...... What you think ?

I have the correct socket to fit the pressure sender if you need to borrow it. Might be easier with the dizzy out, simple enough job.

I do believe a great big set of moles grips also works :)

however they are designed to make a mess and are a close cousin of Mr Stilsons

they designed all the fun out!!!!

and left no space to drill out the stub when you snap off the sender....
