Welcome to the group. Great truck. Already posted in your brake drum thread. I'm working on a 70 K20 myself. I'm not yet ready to start a build thread, but maybe soon. You wouldn't happen to have a build sheet for that truck would you? I'd love to see it if you do.

This is a great site to be on. Lotsa helpful folks willing to lend a hand. I sure have benefitted from their kindness.

Thanks! I’m not sure that I have a build sheet all I have is door tag, paperwork from the last previous owner and possibly the sticker inside the glovebox but besides that nothing else. No manuals nothing

Some plants (mainly Fremont I think) were know for putting them in the seat springs and sometimes under the carpet (if equipped). Might be worth a look.

How do I tell what gears I have in my rear end and front axle?

Re: New to this group 1970 Chevy K20
 

Unless called out as different on your SPID, in '70 the stock gear ratio was 4.57 and is probably what you have.

4.10 is a possibility or 5.13. In 70, those likely had a SPID call out. Your SPID will tell you if you've got a locker. If you do, there's likely a metal tag on the diff bolts.

The front Dana may have a tag too. If it does, it'll likely have the gear ratio on it. The front and rear ratios match.

Of course if you pull the cover you'll be able to see the ring gear which has the ratio on it.

Welcome! My grandfather purchased a 1970 K20 new, and it was rough but alive around 8 years ago.

My dad purchased my 1970 Blazer new and I am currently performing a frame off restoration on it.
