The idea of using the existing face of the ST Pod as a face plate to mount the new gauges in to place, didnt work out as planned, so it was back to the drawing board to figure out a new way of fitting the gauges in place, and thanks to leemaxed who told me when fitting his he had encountered the same difficultys and got around it by purchasing two single gauge pods, and fitting them in to the ST pod at an angle to maximise the viewing of the gauges.so i purchased two single gauge pods which arrived on friday, i then decided to cut the backs from them to allow maximum clearance and ventilation to the gauges and cables inside the st pod 



i then sat them in to the ST pod thinking that their would be enough clearance on the dash for the bases of the single pods to sit on the dash and face out through the st pod face.


unfortunitly the bases on the single pods were too tall to rest on the dash and allow the pod to clip in to place above them, so i got in contact with leemaxed again who informed me that he had gotten the same model of single gauge pods as me, then purchased a longer M5 bolt,
turned the two single pods on their sides, removed the bases from both of them and bolted the singles to each other.
so i done exactly that and it was a brilliant help in positioning them and gave great clearance to the underside of the pod too.


the next step was to find a way of keeping them in that position within the pod,
their is many ways this could be done by either glue, or silicone, but i had already got the face plat from the original ST pod gauges and no other use for it,

so i began to experment with it, cutting bits off to see if i could create some sort of support bracket to hold the two single pods in position,
unfortunitly i slacked on taking many pictures of this section in the modification process although i have edited the picture below to help describe the section of the plastic casing i used.
in the image below you will see the image i have coloured in various sections to help explain how i created the bracket to support the gauges in place,
the section with the yellow outline is the shap i cut out and used to supprt the under side of the pod, then the red box section with the X on it, that is the section that i cut out and glued at an L shape to the under side of the first section.
the solid red section i cut away and threw in the bin.

below is a picture of the end result. from cutting out the bottom section to create a flat plate to support the gauges underneath, and i left a lip on the rear to help grip the rear of the single pods too,

i also drillet a hole in the centre to allow the longer M5 bolt stick through and i plan to fit another M5 washer and nut to the end of it, so as it is 100% tight and secure,
i glued this section to the bottom of the gauge support, then fitted double sided sticky pads to the single pods where they made contact with the panel.
the results can be seen in the following images:



depending on the gauges fitted in the pod, you may also need to cut out a section of the pod surround to allow the boost pipe fitting to sink down in to the dash, i had to remove a square section but i have failed to take any pictures of this being done,
but once their is enough clearance cut out, the pod will sit snugly in to place in the dash as can be seen in the following image:

the next step of this modification is to fill the space between the two gauges in the front of the pod,
i have purchased some 1.5mm clear perspex from ebay, and i plan to trim it to the required shape then wrap it with some matt black vinyl to blend in with the rest of the dash.
the gauges are not operational yet neither,
i have to purchase the self sealing 1/8NPT adaptor and a oil pressiure sensor T piece, but due to the limits on the ammount of images that can be uploaded per post, i will need to complete the rest of this guide on another post at the end of this thread.
thank you for looking.
