I want to swap my 15" wheels from my 2WD van to my syncro. To
fit the 15" Wheels to the 2WD I needed to get longer studs in
rear and buy longer bolts up front. I have two questions:

1) Do 15" wheels just bolt on to a syncro (front and rear) or
do I need to get longer studs (front and or rear) just like a
2WD? I do not currently have 15" wheels.

2) If I want to put 14" wheels (non alloy) back on my 2WD van
will I need to swap out the longer rear studs that I upgraded
to or will the longer studs work with stock tires? I am OK in
front as I have the shorter bolts still. I suppose I could
cut the studs but it would be a shame.

Thanks,
Chris
