ok ive got a gslse housing with no gears or 3rd member, i want to find a complete one but so far all i can find is pieces of gslse 3rd members,. so my question is can i get an fc na 4;10 ratio 3rd and swap it in with no change to the axles or anything?
also was wondering if fc 3rds are aluminum or steel, thanks
ive searched and some people were saying that it might fit in there, but i wanna know from someone whos done it,

i know its little to no gain especially if its not aluminum, but i just cant find the proper gslse rear that i need
thanks
Paul
