Lower frame engine dimension and sizing GMC SAFARI 1991

[Vad12]

Is anybody know dimensions or size of a frame where fits engine (lower frame)
maybe some manual or scrapbook with sizes of a frame?
p.s.front wheel drive

[Kidhauler]

None of these vans are front wheel drive.

Try giving more detail and possibly someone could help

I think you will just need to measure it up....
The size can vary depending on where you look at it...
I imagine by Front wheel drive, you actually meen All wheel drive?

[Vad12]

Control sizes of a frame?
Car drive rear! 4х2 Leading back bridge!

This is all I have.

These vans do not have a separate frame from the body. They are a unibody the built in frame rails are 2x4 inches. The engine , transmission and front suspension mounts to a subframe that bolts to the front of the van. I hope this helps it is hard to tell exactly what your asking with the translator your using.

That sure is handy. Was there a 2000 All-wheel-drive diagram where you found this one?

Or other years?

Nice diagram.Took a copy for my photobucket account.

If it where mine,the minimum would be square tube 2 x 3,but even better like 2 x 4.

In the shop talk section,suspension sub section that is building a complete frame and mounting a Astro body to it.It is one of the most elaborate profession home builds I have ever seen for a Astro van.I think he used 2 x 3 square tube for his.Might want to check that out.Mark really does know his stuff.Has CNC design capabilities.

Before I forget.Astro vans have a very wide wheel base.I found that out by trying to dolly tow them with rental U-Haul dollies.The only way they fit is by using the narrow spare tires on the front.
