A few thoughts- because the belts are wider, you may need to shift the
engine
and ZF backward a little to clear the firewall and access cover, and
remember
when running a flat or toothed-belt drive, the accessories may be driven
backwards depending on the design. Some waterpumps and most alternators (due
to
the mount of the brush in the back) are designed to run in one direction, so
this may increase the expense if you convert, but does save the complication
of
buying & changing pullies on the accessories if they're all-new. I think
rotary
A/C compressors are OK spinning either way. A few mfgrs use
cast-and-machined
aluminum pulleys which can be significantly weaker than steel, or aluminum
pulleys made from plate. Some older cast/machined flat-belt pulleys have
cracked
in use- usually leaving the Pantera dead on the side of the road unless one
carries spares & tools. This's one reason why I made my own- no one could
guarantee the available alloy pullies were strong billet. Good luck- J
