Purchased a Diesel Geek Short shifter today to make room around the TSTAT housing....
Also ordered a cast MK3 12V TStat Housing so that I can go back to original equipment hoses...Again, can only go to original hoses if short shifter kit is used.
We shall see, and I will update this thread with pics when they arrive. Fingers crossed.
Oh,
And also ordering a custom front mount for mk3 12V o2m swap. Will post those pics shortly. 
Ooooo some fun stuff came in!!
Front Mount (generalprinciple.com/02M). Thanks Shawn!
02M short-shift (to allow room to re-install original mk3 tstat housing) from Diesel Geek:
Tstat housing!!! Back to oem mk3 style to get back to mk3 oe hoses. Thanks Eurowise!!!! Came with a new aluminum water pipe, tstat, gaskets, hardware, clips:
Can't wait to see if the short shift kit will do what I think it may-make room for the mk3 tstat housing to be put back in.
If you recall, this swap requires use of mk4 24v tstat housing due to shift linkage getting in the way of tstat outlets/hoses.
If you don't know, the 24v housing is very different and requires custom hoses, not just 24v or 12v hoses.
Started today. The new front mount is incorrect.
What a mess when there is no front in it!
Turns out the mount bracket is NOT incorrect. It's just that it is EXTREMELY tight to get in/out.
You must lower the front forward subframe to get enough room for the bracket to slide in straight and unobstructed.
Remove front mount, lower subframe, install.
Two 16mm bolts each side:
drivers side.
Lowered:
So officially got this front mount in.
Easiest just to take the front clip off
In order to get a socket on the trans bolt (red dot) you'll need to remove the oil cooler.
I pulled my water pipe because I am replacing tstat housing-which made removal of oil cooler even easier (due to inlet/outlet coolant hoses).
Mount looks solid and up to task.
Next project today is the short shift kit.
Stay posted...
Ok, I guess I fixed the mk3 vs mk4 tstat housing "issue".
My only disclaimer is that I haven't actually put the hoses on but it appears that with the short shift kit installed you can clear the linkage (only 1/2" to spare).
Seems it's at its closest when in 5th gear.
Ordered new oil cooler and looking at mk3 hoses next. Maybe a samco kit?
Ok so I put some new stuff in today...
New oil cooler just because: #376726221 @ 38.88
Two oil cooler hoses:
021121096
021121058A
These are the hoses that go from oil cooler to engine block and from oil cooler to water pipe.
Might as well replace while its out.
Back to OEM MK3 hoses!
CHR0018P: Contitech Upper rad hose
CHR0101P: Contitech lower rad hose
Two Oil cooler seals:
038117070 (oil cooler cap to oil cooler)
038117070A (cooler to block)
Realized I cut up many of my hoses in attempts to make it work during my 02M project so I had to order more:
1H0121157H: Heater Core to TB to Head
1H0121063B: Tstat Housing to Aux WP to coolant bottle drain.
1H0121073C (for reference only) is the other hose that comes out of the aux water pump (mine is still in good shape).
Some progress pics:
Oil cooler and new water pipe:
Trying to tidy up this wiring mess!
Thermostat housing cover that the folks at Eurowise sent along with the water pipe and tstat housing. For reference this part number is an OE part (unsure what car it came on as stock): #357972279
And
And check it out! Hose fits on to the mk3 tstat housing with room to spare!
And
Pics with both upper and lower hoses connected:
And with the new location of the maf housing and filter it's way tight but still fits:
