Its a good price. Ive paid more!!!
Make sure its a 410 case tho. Theres a lot of miss matched 410-413's out there.
Ive personally bought 2 cases(definitely from a 410) only to find out they were actually 413......and no bloody good at all for making 4.16 gearsets....!
Hence Ive currently got 7 sets of transfer box cases in me garage!
The only def way to tell is to stick in low box and turn the input shaft, and measure the number of turns on the drive shaft. (ie check its the correct ratio for a 410)
Remember, 413's and 410's all had tranny brakes, and some 413(spanish) had rear axle parking brakes, so you cant tell externally....
