HBF comes out of retirement

[HBF84]

I was thinking along those lines too but it didn't match up too well.  When you go online to buy a new instrument panel, some have the hash marks and some do not.  I wonder if the ones with hash marks are supposed to be in trucks with manual transmissions but I did not see any indication of that.

I have the 1984 owners manual and have scrubbed it pretty well but of course, haven't come up with the answer.

Gary, I have the 1984 owner’s manual on my computer I could put it on a thumb drive and send it to you. I scanned it a couple of years ago, just because I got a new scanner and wanted to try it out.

[Gary Lewis]

That works for me.  Or, do you have Google Drive, or Drop Box, or One Drive?  If so you could put it on there and give me access to just that one file.

Through the years, I have asked regarding the "hash" marks. They are the same and seem to have nothing to do with being automatic or manual. They are the same regardless of engine or rear gears.

I asked a retired Ford engineer and he did not know why and guessed it might have to do with calibration?

In my truck is [was?] a NOS F600/800 medium duty speedometer which goes to 999,999.9. It is a replacement [service] unit designated by having red colored digits for the tenths. It, too, has the marks.

The metric versions, which go to 999,999.9 kilometers, do not have the hash marks.

The speedometers with resettable trip meters do not have the 35/41 marks, due to having the odometer set higher to make space at the bottom for the trip meter.

I have attempted to see a pattern, unsuccessfully, in comparing the standard and metric [roughly]:

   10/15 MPH = 16/24 KPH
   35/41 MPH = 56/66 KPH
   67/78 MPH = 107/125 KPH

The dash mystery remains...Interesting input!  Hopefully we learn a solution.  Maybe we need some brain food?  Turns out, that there was an MRE left back in the bed a decade ago and I did my best to see the use by date, but it had faded.  Anyhow, it was delicious!!!









No jalapeño cheese sauce much to my dismay.  But, if you've ever wondered what a bag of Skittles looks like after being left in a vehicle for at least 10 (probably 15 to 20) years, now ya know!

Yuk!  Count me out.

I don't want to poke fun at your state, but I've eaten groundhogs -recently- and I still wouldn't want to eat a WW2 Krat.

Gary I have the 1984 owner’s manual files uploaded to google files. If you would private email me I will give you the information on access.

[Gary Lewis]

Email sent.  Thanks!

Brain trust...I'm struggling finding a Bullnose Era 8.8 rear end with 3.55 gears and limited slip.  It seems like there are plenty of open 3.55's out there but the limited slip is a unicorn.  Or at least the 7 surrounding junkyards only have open 3.55's (or none at all).

I found a door code H6 which seemed to be the 9inch front bolted pinion.  And, several door code 19's.  But, can the brain trust verify that I'd want an H9 door code?  

I mentioned before that I had a lead on a 1994 H9 but on closer inspection there was a large flange coming out from the pinion and the flange held the yoke for the universal join.  I went on to scrounge around the local junkyard for more F150 rear ends and anything from the 90's and on up has the flange situation.  So, then I might have to deal with a new driveshaft length and what not.  

I'd like to keep it simple.  So, is a Bullnose "door code H9" ridiculously rare?  Should I just go with a "door code 19"?

[Gary Lewis]

Yes, certification label H9 means 8.8" 3.55 limited slip.

[ArdWrknTrk]

Why can't you just put your pinion yoke on the '94 rear?

It will have a VSS (tone ring carrier) too, but you don't need to use it.

[HBF84]

Oh...So the yoke would be interchangeable?!?  Awesome!

[ArdWrknTrk]

I would look up the pinion gear on Yukon or something and see if those years have the same spline and length.

It doesn't make much sense that Ford would have changed it.

[jdavidsmi]

I changed the differential on my 84 with one from a 96, 84 no flange, 96 flange. Everything bolted right in and the drive shaft fit like a charm.

This change was from an 84, 3.55 open to a 96 3.55 open, 8.8.

Well, HBF has been in the shop for a bit but finally broke free this weekend.  One of the first projects was to dissect out the build sheet from underneath the bench seat.  Can anyone help with this interpretation?
