I'm not 100% sure but I think Thorley has two different part numbers, one for 2wd and one for 4wd.
The set I'm selling is 302y-fed-c for 2wd

301y-fed-c is for 4wd

I'm not exactly sure what the difference between the two is...most likely the crossover pipe which wouldn't take much to mod to work.
Hope this helps.
