yeah....left or right is easy to do.
241 is most common for the chevy, but i prefer the fixed yoke jeep 208's when you can find one. problem with the jeep case is you need to put whatever chevy input shaft you have and run a spacer/clock ring.
if thats to much of a pia the the cake setup is a 4.3 s10 trans and t case. it has the weaker 207 in older units with manual shift t case
you can build a 700, get a 241 and put a slip yoke eliminator in the 241 and have a very stout setup. the 241 is stouter then the 208 as well when sye is installed
