oil pressure gauge - aftermarket?

[Timmmy]

Hi All

I want an analogue aftermarket oil pressure gauge on my 87 5KTQ and i have
2 questions, or maybe 3...

1. There are 2 oil prossure senders on this thing, one low pressure and
one high as far as I can tell. If I am to put in an aftermarket oil
pressure gauge of the pipe type (oil delivered to the gauge), does it
matter which port I use?

2. If I add a gauge to one of the ports I will need to use a 'T', will
adding this affect the performance of the existing sensor at all?

3. Threads - does anyone know the thread type and size on those sensors?

4. Has anyone found a good, clean approach to mounting additional gauges
in a 5K? I am not mad keen on pillar mounts aesthetically but they do the
trick - does anyone know if a pillar mount is available for the 5K?

Cheers

Timmy

p.s. After 4 months of weekends, I finally drove my 5K out of the garage
this weekend, and putted it up and down the snow covered roads as I need
to run it in still , and I have not tuned it at all yet. But there is
certainly more grunt there now than there was before :)

So this weekend I should be able to tie up the loose ends and get it back
on the road :) :) :)
