Back in the ‘90’s Mopar Performance sold a kit to convert Daytonas to V8 & RWD. The kit would work on any of the then production K-based chassis (J-P-G, Lebaron, Shadow, Daytona, etc). It was a different K-member and a pair additional crossmembers. It converted the car from the stock rear steer rack to a front steer unit using a 2WD Dakota rack.
The builder had to fabricate everything else. It was intended to allow racers to convert the production FWD cars to compete in NHRA SS/GT (I think it’s that class anyway). The cars were expected to be tubbed out in the back using one of the commonly available back half kits out there.
There is a guy in PA doing street based conversions for Daytonas. It’s Exline Custom Auto, LLC. He has some pictures up on his site of the conversions. That might give you some ideas for your VW.
I don’t know how much room there is under the hood of your Golf or how/where the rack is mounted. You may need to recess the firewall to make room for a V8 and fabricate a trans tunnel. That will effect seating and controls positions in the interior, then you still need to fabricate a live rear axle suspension, exhaust clearance, etc.
This is just what’s popping up in my head right now. Not saying that it’s impossible, just that it won’t be a walk in the park either.
