I need a quick answer, please. Will HD alum. from GM fit a 2nd gen truck?

 

Depends on what HD alum. is....

 

If you mean Heavy Duty GM aluminum wheels they might fit if their diameter is large enough to clear your rear drums, usually 17" or larger.

Ford super duty wheels will not fit Dodge or GM 3/4 ton bolt patterns. they cahnged the lug pattern in 99 IIRC.

 

These are the regular 16" polished rims like comes on all the late model duramax trucks. I went and looked at them, look good, tires are wasted, now I'm not sure that they will clear the rotors, the offset looks wrong, I think I'll pass on these....thanks guys!
