Well. I also want a straight axle in front,but I think the mods I saw till now are too difficult for me....I mean ,I read many articles about people installing a straight axle in front but I cant do it,cause I dont know where to find the parts.For example where can I find a straight axle that will match my sidekick? And the rest of the parts to connect it ? and some guidelines ? I think its a bit confusing for me for such a mod,so I ll wait for the Calmini SAS kit.
In the meantime,I m still happy (and safe)  with the Anvil .Soon I will replace the fake spanish CV shafts with Japanese green ones ,and if I break one ,I ll try to do the modification Hagen proposed,with the Ford CV shafts.My only fear,is that if I make stronger CV shafts,maybe a possible damage will go deeper in the differential instead of just breaking  the CV.........
