More Suburban questions?
 

Did all Suburbans during the late '70s have the 3rd row seat provision (anchor) in the floor?

Also is the driveshaft the same or different length in a c-10 longbed with t400 as that in a Suburban with 454?-both 2wd.

No - third seat was optional. The provisions were there only for vehicles where the third seat was purchased.

Driveshaft length - not sure, since I don't have a chart in front of me. Do both the pickup and burb have the same engine (may not matter)? Do they both have a TH400 - you didn't say.

Keith, sorry I didn't make it clear in my post. Yes, taking into account that both vehicles have the 454/t400 trans.

there is about a 2 inch difference in the wheel base so its probably a different length draveshaft as well. c-10 longbed 131.5" wb, Suburban 129.5" wb
