Just bought a 1980 4X4. Found out it had a cracked transmission case. Previous owner had coated the whole trans in aluminum colored silicon sealant to hide it. lasted about two weeks before it started pouring out the gear oil.
I bought a 5 spd to replace the cracked 4 spd. Complete setup with transfer and driveshafts. I want to try the dual transfer setup. I am not a super heavy duty rockcrawler
1. Should I keep the stock 2.28 in both transfers or add the 4.70 to the rear one?
2. Since the 5 spd transmission is 5 in longer than the 4 spd and the additional length of the dual cases, will I have to move crossmember mounts back since the transmission length difference to use Marlins dual cases crossmember?
3. When I have driveshafts lengths changed, should I use the front CV from the donor unit on the rear driveshaft and if I do will it go on transfer side of driveshaft?
4. I have had 2 FJ40's, 1 FJ60, 1 FJ80, 2 4runners, and 3 pickups. Other than lifting the FJ80, I have allways kept them stock so modifications are new to me. Please help with concerns, commnents, and best bang for the buck. This truck also will be used on icy days when I cannot ride motorcycle.
