Early/Late Production Truck

[MoparBill]

I found the window sticker for my truck, I just picked it up, and it's my first diesel truck. I have read the early/late split on the Powerstroke is the first week of December 98, my production date per the window sticker is 11/24/98. However mine has a mix of early and late idiosyncrasies. Such as, mine has the door instead of the fender PSD badges, I have the lumbar, and the catalytic convertor. One of my questions is about the "front intake airbox", mine is fed through the fender which one is that? I also read that the down pipe, the turbo, the intercooler, and the injectors are different, how do I differenciate the 2 types? Are there part numbers or design differences? I know its a lot to go through, but I appreciate any and all help.

your truck is the ultimate hybred. you have an early 99 with some late 99 features. mine born is 09/98 only has early 99 goodies on it.... the fender fed airbox is the early design and was recalled by ford due to all the problems it created. toss it as it is probably broken all ready. as far as i know, the intercooler and downpipe are not different. the turbo and injectors are. early 99s are 120cc and late 99 on up are 140cc. the idms are different 110volt vs 120volt. hpops are different, 94-early 99 use a 15 degree hpop, where late 99+ use a 17 degree. the stamped steel intakes on the head are also different, late 99+ have a 3 inch diameter. therefore the intake spider on an early 99 is different also. you can not put a late 99 turbo on an early 99 unless you change out the up pipes, pedistal, and intakes. early 99 spiders are sought after by obs owners wanting to intercool their trucks, because the early 99s share a lot of the same external features.

Good to know, 307.

FYI... there are some suspention differences also... front springs/u-bolts, track bar, steering components. And some of that might go into 2000 model year trucks. Found a 2000 F250 with the older '99 style u-bolts and plates... everything else, turbo, motor/up top stuff is new style, but it has old u-bolts.
