Hello,

Just keep in mind that if you simply change tire diameter to
change the final drive ratio it will effect how the Van performs
around town.  You're moving the usuable engine rpm range
up and down by only changing one part of the equation.  Sure,
Mark will have good highway cruising but it *may* be a bit
sluggish at lower city type driving.  Then again, with a GTI
stuffed in the backend it should produce enough torque to
compensate.

PS- My info shows that Diesels Vans came with a 5.86 not
a 5.43 ring and pinion.  The 5.43 ratio is a fairly common
002 IRS Bus ring and pinion set.  The Diesel trans is apparently
a mixture of 002 and 091 parts and therefore may have come
with the 5.43 set. Who knows?
