I have a custom 1350/1354 doubler that I was planning on using in my truck but my build is taking forever and I need the money more then I need the doubler. I did not make the doubler but I did remove the 4 gear planetary from the 1350 and replace it with the newer, stronger 6 gear planetary. Included is a 1354M as well as both a factory 1354 shift linkage and 1350 shiftlinkage. $500.
Would prefer pickup in Connecticut, but I will ship on your dime.
Newer 1354 planetary set that was swapped into the 1350.
