6 bolt swap- water line ?

[JET]

Alright, I am basically done with a 6 bolt swap into a 95 GST, but I am missing a spot to hook up the return line for the turbo. The old one went into the side of the block, which the 6 bolt doesn't have. I did the RRE swap, so I didn't need all of the parts to swap like the magnus version. I still have all of the 7 bolt water pipe, t-stat housing, etc.

I was looking at welding another bung on the T-stat housing next to the return line from the oil cooler if I had to, but wanted to see if there was an easier option.

Thanks!
