75 k20 scottsdale... what years swap parts?


The fenders on my truck right now are too nice to cut into, so I am looking for a junkyard set. It's a flatbed, so no need to worry about matching the bed, I just need to know which years/models are the same size and will bolt right in???

'75 k20 chevy scottsdale, 350 w/a manual 4 spd, 14 bolt rear, 3/4 ton. It's got 8 inches of lift and creeps in granny low w/the old set of 33's that are currently on it. I figure the drivetrain will have no trouble handling the 36/12.50's I just got. Rear clearance is no problem(flatbed), but I'd like to trim the lower corners of the front fenders back even with wheel-wells to give me a little extra room.

Wish I had a pic, but I'm guessing you guys know the model of truck I've got.

With 8" of lift you should have no problem clearing 36" tires... even pushing the articulation a bit I doubt they would rub. 6" lifts clear 35" tires just fine. Have you tried them on yet to see how they fit?

I really need to get some pic's, as for the lift, I am going on what I was told when purchasing it.

It looks as if 36's will clear, but with very little to spare. The 33's on it right now have plenty of room, but I'm worried the 36's will rub the fenders, as there has to be some amount of play in the front axle. It looks like there is about 2 inches of fender that could be removed, w/o having to cut into, or moving the inner wheel-well.

I know fender chopping isn't usually the first option, but I'm putting a $400 set of goodyear military H1 tires on a $800 truck and don't want to mess them up. I'm hoping to find a set of extra fenders for cheap at a junkyard, so I can go back to the stock look when I'm not mudding.

i'm not sure exactly what years will bolt on. what you want to do is get yourself a catalog with replacement body parts. then you'll see what range of years fit your truck.

8 inch lift should be plenty for 36's. I know the 80's chevy military trucks came stock with 36's....

They came stock with 31" tall tires of two different specific sizes.
Later on someone figured out with a bit of trimming and some stock GM 16.5" wheels you could put some 36" HMMWV tires on and go over 50mph in them.
