1979 J20 Fire-truck to truck conversion

Postby Z-240071 » Sun Oct 15, 2017 2:04 am

Hello all :)

New to the forum and first time Jeep owner .
Just got me a 1979 J20 firetruck that i plan to bring back to how it started life - as a pickup.
I live in Norway , and this truck has spent its life as a small-town fire-truck , way north in the country .
It has just over 14000 original miles on the road . never driven on salted winter roads , and has been kept stored
in a heated and dry fire station garage until this summer. Seem to have been maintained properly all the years since
1980 , when it was built into a firetruck.
Have not seen many J-trucks in Norway , and could not find any other for sale to compare price with.
But i fell in love , and paid about 5000 usd for it . dont know if i over paid , but i had to have it :D

Hope to get usefull info , tips & tricks from all you members with knowledge of J-trucks :)

I will try to post some pictures . please correct me if i am doing it wrong.

Wow! That is a nice truck and complete. I think you paid a reasonable price for what you got. Will the bed Topper un bolt or will it need cut off? IMO, I'd get rid if the Train Horns on the hood and remove the pump from the front bumper :mrgreen:

Nice to know the price was reasonable :) It was an auction with starting price at 300usd , and i got a bit carried away :mrgreen:
Yes the topper will bolt off. Not sure how big holes it will leave , but the plan is to make something nice in stainless steel
or aluminium to cover them up . maybe a profile around the bed top of some sort.
The big horns and pump of course have to go !
It has an "special vehicle" title , that has limitations on top speed among other things (49mph) .
In order to get title as a pickup , the pump must be removed. Also the big search light need to be removed.

It starts and runs , but i am told it runs rough .
I think i would like to replace the carb with somthing new .
Any good replacement available ? maybe somthing with a bit more preformance ?
Also thinking on a 2" lift and a bit bigger tires .

I would let the top speed be 49mph and leave it that truck is way too cool

Congrats on your score. The Holley 2300 (350 or 500 CFM) is a good replacement for the stock Motorcraft 2100 unless it has been changed up already. You have more pictures available?

Nice project! Yours to do as you wish. But searchlights and fire hoses? That would be a blast!

Im sure every boys dreams at some point to have his own fire-truck :D
But it will be quite useless as a truck , and i would not have much use for it .

:) OK , so i finaly got to start on my J20 today.
After getting it started in 0˚F and snow , i started removing the pump. It´s a bit more messed with then i anticipated . But nothing major . The grill is pretty messed up , to fit a waterpipe throuh . The radiator has been raised to fit a driveshaft between the crankshaft belt pulley and the pump. They have also put spacers on the hood locks , and made some panels to narrow the gap between the hood and the side fenders.
Also cut some pieces out of the panel under the grill.
It will take some effort , but i luckely NO rust to repair is found :D

So now starts the fun part for a J-truck noobie : getting parts.

I would much appreciate tips and links if anyone know where to get what i need.

My shoppinglist so far

New grille
Interior floor carpet
Spark plugs
Spark plug leads
Engine gasket kit
Distributor cap & rotor
Points & kondensator ( or electronic ignotion ? )
Fluid for quadra-track (dont know what to use)
Air filter
Oil filter

Is the corner panels in front of the front wheel fender flair possible to new?

New Grille- Ask the guy in France. Froussard I think?
Spark plug leads- Source from MSD 8.5mm wires
Engine Gaskets- Fel Pro
Distributor cap and rotor MSD
Should not have points
Unsure of fluid
AC oil filter
Hard to find new panels. Used in good shape is possible

I found out , as soon as i lifted the distributer cap :D
Did not know they have electronic ignition.
gusess i was fooled by by the condensator mounted on the distributer .
i have converted some cars before to aftermarket electronic ignition , and always removed the condensator.

I have removed the pump and "reverse engeneered" the front of the truck .
no big issues but , will need some welding to get the front looking nice .

Oh Man. Looks like original hoses and clamps on the fuel filter.

Long time no progress..
Finaly moving forward after a cold winter.
Almost ready to remove the topper and the water tank .
Pics : https://imgur.com/a/9ASpvRJ .

I have a big lot of parts on the way over the pond :)
Cant wait to get it running as it suppose to !

Got me a set og 16`(X-7 i think) wheels for next to nothing , from a lady that could
not tell me anything about them. Not even what car they sat on . So i took a chance.
They came with good tires in 245/70-16.
I would like a bit bigger and more «offroadish» tires , but i am not sure what to do.
The offset on the rims makes them fill out the wheel arch about as far as i can go.

Pics of stamps on rims backside https://imgur.com/a/8Lqprrc

I would like to ask the crowd for tips and opinions on what to do with the wheel/tire issue.
I have found a cheap set of 16x10 rims with et -38 , off an old Dodge ram powerwagon.
Anyone who know how they will fit the j-20 , and what kind of tires i can fit ?

All advice and opinions are greatly valued :)
