the part i need are dana 44's front and rear 373 gears for a 77 k5 blazer.
the other thing is a automatic steering column and turbo 350 help. The tranny problem i have i drove the truck once outa ta buddys houseand back ran great no problem at all. the next week it dont move at all. what do i do or check first

trans fuild

already done that new fluid and filter every thnig is new in that tranny

Just because the truck didnt move doesnt mean its a transmission problem. If its a auto tranny then it has a 203 transfer case and this could be wear your problem is. First and for most make sure the transfercase isnt in Neutral. Now if the transfer case isnt in neutral i'd open the t-case and check to make sure the chain is on. If everything seems to be in the upped up try both the drive shafts and check for bad U-joints. If the drive shafts are in working order then your next step would be to open up the both the differential covers and check to make sure nothings broken in there. Give these things a try and see what you come up with.
