That is great, but I was looking for "curb weight", or something like that. the Danish import and registration/ inspection rules are a bit odd?

[zieg85]

Would a certified scale at a truckstop work???

[C-10stepsideBEEF]

No, been there done that...
In Denmark pickups and vans can be registreted as "vintage vehicles" and then the import tax is less than new vehicles.
And if my 1975 C-10 stepside is allowed by Chevrolet to exceed or tie 5511lb the import tax is zero "$" or in this case "KR" danish valuta.

My C-10 is born with a straight 6 but swapped to a smb V8 at some point, And because of that the import tax is very expensive.

Please forgive the misspelling.

So they tax on how much they can potentially carry including the weight of the truck just shy of 4400 lbs.  The tax is less if it is heavier??? I don't get it

[Irish_Alley]

i take it you have no RPO sheet in the glove box?

[Irish_Alley]

ill add this. in order to have the HD springs front and rear you have to have the HD brakes

JB1 BRAKE, MANUAL, DISC/DRUM, 4300 LBS
JB3 BRAKE, POWER, DISC/DRUM, 4600 LBS
JB5 BRAKE, POWER, DISC/DRUM, 6400 LBS (HD)

im just going to point out what i see
http://forum.73-87chevytrucks.com/smforum/index.php?topic=28592.0


i know its hard to read but it says

jb3 11.00"x 2.00" and jb5 11.15"x2.75"

measure your rear drums and it should tell you what brake system you have if you have the 2.75" pads then its the HD. if you have manual brakes you dont have to measure anything cause you have the JB1


or you can look at the booster, JB3 will be a single while JB5 will be tandem (or dual)
JB3

Single Diaphragm Vacuum Booster

JB5

Tandem Vacuum Booster

the G50 HD rear springs totaled 8

this is about the "big 10" but you will see it still hold water for yours
The base 4,900 lb. rated C10 used the following components at minimum:
-   1,550 lb. capacity front springs.
-   1,550 lb. capacity rear springs (consisting of 4 leaves, and having a length of 52” and a width of 2.5”).
-   Front and rear tires with a load capacity of 1,470 lbs.
-  Manual brake system (the 4,900 lb. rated C10 was the only pickup in the entire C/K10/20/30 lineup to use manual brakes. The front disk brakes had a diameter of 11.86” and a thickness of 1.28”. Rear brake drums measured 11”x2”).
-   Standard LD4 250 1 bbl. I6 engine w/M15 Saginaw 3 speed manual transmission.

The 5,300 lb. GVWR required the following minimum additions and/or substitutions:
-   Option code J50 light duty power brake system (front disk and rear drum specifications remained the same as shown above).
-   Option code M20 Chevrolet CH465 4 speed manual transmission (recommended at 5,300 to 6,050 lb. GVW levels when LD4 250 1 bbl. I6 engine was selected; M15 3 speed manual transmissions remained available w/larger engines).

The 5,400 lb. GVWR required all items necessary for the 5,300 lb. rating plus the following minimum additions and/or substitutions:
-   Front and rear tires with a load capacity of 1,610 lbs.

The 5,600 lb. GVWR required all items necessary for the 5,400 lb. rating plus the following minimum additions and/or substitutions:
-   Option code G50 heavy duty rear springs (2,000 lb. capacity for this application. These springs consisted of 8 leaves, and were 56” long x 2.5” wide).
-   Front and rear tires with a load capacity of 1,790 lbs.

The 6,000 lb. GVWR required all items necessary for the 5,600 lb. rating plus the following minimum additions and/or substitutions:
-   Option code F60 heavy duty front springs (1,625 lb. capacity for this application).
-   Option code J55 heavy duty power brakes (this system replaced the lighter capacity J50’s single diaphragm brake booster with a dual diaphragm unit and included larger 11.15”x2.75” rear drum brakes for C10 applications).

So I have been looking at this for a few months now, and the data is not good enough to solve my problems.

Thanks for the help all of you.

Bottom line is now to swap the 350 v8 for a 250 inline6 and redo the import papers, then the truck is a legit "classic" and I will get all the bennefits of owning a vintage vehicle in Denmark, (gov. inspection every 8 years instead of every 2 years, lower road tax and low insurance, plus no import tax).

Main problem is the original inline 6 250cui are rare in Denmark and Ive been searching for one since june, with no luck.
