Yeah mine is from an 06 Solstice. I used the Verossa shifter housing. It’s only 149$ on amayama trading co. The shifter is like 100$. Now shipping will be more since it’s coming from Japan but they ship fast. Shipping looks to be 65$. You could also just buy the shifter housing from amayama and get a shortshifter from eBay and save a bit if you get a cheapo or spend a lil more if you get a cube speed. All that to say, it’s not 450$ 😛 . I have a stock W55 shifter I’d sell that would work. Need to find it.
Will the truck trans even work in the cars? I haven’t seen anyone go that route. Something about the tail shaft isn’t suited or the shifter? Don’t remember what the deal was.
I was able to find an oem jzx shifter housing on ebay for 200 free shipping so I grabbed that last night. And today I picked up the only 06 solstice trans I could find within like 400 miles. Paid $650 plus $100 core. And yeah you can get a much cheaper shifter, my $450 was the oem housing and shifter, if we have to....overnight parts from japan

. I'm prob going to pick up a short shifter, personally not a fan of the canted w55 shifters.
Yeah there's people using the ar5 from the colorado. Check the pics
here you can see the tail housing is a lot different. And yes if you dont want to cut your tunnel you'll prob have to buy one of the rare $400 remote mount shifters to place it in the is300 chassis. They seem to be a bit cheaper and way more plentiful.
