but it is not hard and has been done many times.
I suppose “not hard“ is a relative term, based on one‘s mechanical experience. Plenty of folks here are just regular folks trying to keep their old car alive.
The exhaust and heat shield need to be dropped.
Need to buy the Polo shift box or mod your current to mate the newer shift box to the body.
Think about shift knob compatibility.
Remove stock parts and install newer parts.
Adjust and drive.
I did the above in my driveway, on my back. The only reason I did it was because my dp flex broke, and I’d read nothing other than rave reviews. I modded my stock box… I didn’t want to spend an extra $150 at the time or wait for parts. Not hard, but I consider myself an ok mechanic. With the work involved, I’d recommend just rebuild the stock shifter, unless you own a race car…. My B4V with good parts and a kharley short shifter feel just as good, IMO.
I’d bet the investment would be $200+, but that doesn’t include the Polo box cost, if you want the easy way out.
