frame dimensions

[ProjektDirtFab]

I would also like to peek at some 73 to 87 frame specs. Some good detailed body builders blueprints. The only ones i can find dont have very detailed measurements.

Although that one pic above states 74 to 70...was there an overlap in production?

Anyway yea if someone can share some 73-87 specs that would be cool. Building a 2x4 frame now and would make things go a little faster.

Thanks

Edit: i did find these but the wheelbase doesnt match another document i have. 117.5" vs 131.5"
Can someone confirm the year of this frame pic or at least the true wheelbase of a 73 87 2wd swb.

Gracias!!


Edit again!!! Answered my own Q. The bigger wheelbase was the longbed...duh. well heres the shortbed blueprint for the later year c10....let the custom frame commence!!!
