Default elongating TGV for an 07 WRX

ok i have an STI manifold going on my 07 WRX and i would love to do the TGV deletes
two problems A) my 08 sti manifold will not mate up to my wrx TGVs due to the bolt holes on the back being a 1/16th of an inch off
Trying to find 07+ sti tgvs is like trying to find a pot of gold at the end of a rainbow even grimmspeed has a delay on them
I heard that you can make the 07 wrx TGVs mate up by elongating the bolt holes. i was wondering if anyone has done this, and how long does it actually take
if you guys have a link to a DIY for this process i will be so happy
thanks

Its actually pretty simply, just take a drill bit and oval it out. Try to keep it in an oval shape and not a circle or else you might accidentallly make it too big thus letting the flanged head bolt slip through the whole. Whole process should only take 10 minutes.

Oh, and yes, 07 STI TGVS are REALLY hard to come by.

I'd use the appropriate size grinder bit to elongate the holes or a file if you have some time to kill.

I bought a set of 07 STi TGVs off Ebay 2 weeks ago for $40. I still have them and went a different route. I have no use for them if your interested.
