Quoting gaylantvr4:
did you use the 3000gt front knuckles as well?
Yes and that was an even bigger PITA, although it possibly would not have been if we had found a complete RVR donor car. The 3KGT knuckles increase track at the front as well which seems to make the VR4 axles too short. The RVR passenger side axle (that's the driver's side for you guys) fitted perfectly. Unfortunately we couldn't locate the other side to try so we ended up having to make a sort of spacer to get the VR4 axle to work. Took three attempts and two destroyed wheel bearings to get it perfect. If the other RVR axle is the correct size though it would actually be plug and play. I really should try to locate one to confirm. I'd feel happier using the correct sized axle than a band aid spacer anyway!
