D90 frame stretched to fit a Series 109..Pros/Cons

Has anybody stretched a D90 chassis to fit a series 109 or 110?
I was thinking this would be a lot easier then using either a Disco or RRC chassis
I know there are some folks stretching these for 130 builds.

Not very cost effective I'd think. There are a ton of RRCs and Discos around in junkyards, and probably only a handful of D90s in junkyards. I've seen quite a few using RRC and/or Disco frames used for Series hybrid projects.

It can be done... But you might just consider using a 110 frame instead. In addition to the front tub mounts being different, the rear overhang behind the axle is shorter on a 90 than a 110 as well, so it would have to be stretched there too.

They are not compatible, it would involve a TON of work to make it all go together. The curves in the frame are way different.
I have seen it done, mainly by welding a crap load of angle stock all over the place.

So as I understand it with a D1 / RRC frame I have to totally replace the body mounting and stretch & add a cross member= time and monies
With a D90 frame don't I just need to stretch & add a cross member?

Bill I assume you are referring to the 90 frame?

See Bill's post above... It's not just as simple as stretching. Adapting a d90 frame to a 109/110 would be no easier than using a disco frame, stretching it, then cutting off the frame beind the rear spring buckets, then making a new frame up to the rear crossmember. If fabrication is your thing, go for it. If not, save yourself a lot of time and just buy a 110 frame

Not really. A D90 frame has completely different bulkhead and body mounts than a Series. You'd be cutting off the bulkhead outriggers, the tub mounts, the entire rear chassis, and probably some other stuff I can't think of. Then you have to buy those bits new and reweld them in place, being sure that they all line up properly.

Bill he could actually leave the bulkhead outriggers as is. Yes the defender outrigger is different than the series but that is mostly because the frames are different. The mounting and location are the same. However there is plenty of other work to be done.

I thought the defender bulkhead mounted behind the outriggers and the Series in front. Maybe I am confused due to my limited Defender knowledge. As you say that's the least of it...

if you use a RRC lwb chassis there is no lengthening just rear cross member and outrigger changes.
I have a 110 and lwb chassis sitting side by side for comparison if you'd like to come to the shop- about 2 hrs East of you.

Now that' raises a whole different concern! I will need to look into this because should I want to outfit for extended travel I can't risk using a light weight frame

From what I've seen, the factory welds in an extension in the middle of the frame to lengthen a 110 frame to 130. This may only be on older trucks, I don't think I've seen any newer 130's.

Somewhat related, is it of any value to hang on to a RR LWB frame(108")?
A friend is sending one to the scrapper soon.

I don't follow Series builds much any more so I dont really know.

Final note. I am moving forward with a D1 stretch. The D90 rolling chassis had other issues anyway
