i bought mine used only recently, it seems to be a late model 99' with a vin of 1745 (or close to that anyhow, dont have it in front of me..) just turned 61k, bought it with 59XXX
no signs of an engine swap, unless they were very, very clean about it.. (no knurled bolts i can see, scratched engine compartment , or any of the normal stuff you see when an engine is done..) but anythings possible i suppose..

so far as i can tell, the only thing that is different about this engine is the coils..and it appears to have been very well taken care of by its prior owner...
man, now ill have to check the engine numbers to see they all match up.....
