Re: 4L80 V3500 crossmember question?

C/k 30 use a specific height cross member . So 10 & 20 truck units won't be correct height.

If you can fab go for it and weld one up .

Sounds like you have a single hump unit . There were some double jump units but hard to find . And if looking its 85-91 year range In square body trucks for the style cross member .

Also maybe check www.offroaddesign.com out . They have a LOT of stuff for our rigs .
