76 s/t 440 questions

[jlgoetzi]

I just picked up a couple of 76 sno twisters....they are both in need of some work. Can anyone tell me where to find a service manual for these sleds? Also, are there any parts that will interchange b/n a 75 and 76 sno twister? I have alot of 75 s/t parts and was hoping some would interchange....jackshaft, secondary clutch, chaincase?? Thanks.

Some parts will swap, chaincase & gears, yes, jackshaft...no. The secondary will fit, but the 76 ARCTIC is a better choice. Brakes are the same, drive-shaft is different...
