I am a newy to this so please be patient
I have stripped a 1991 sierra 1600 laser estate
and only have metal and glass to lose.
I am looking to build, with my sons, a Mc 442 with de deion suspension
I am a welder fabricator so I am a bit simple in the head.
does someone please have sizes or drws of the bracket to hold the diff onto the steel frame
there will be many many more questions I am sure

Speak for youself mate...I'm a fabby and certainly not thick in the head....I blame that on the resin fumes

It's a doddle to set the diff up especially if you are a fabricator...the diff outputs need to be in centre of wheels

I'm building my chassis to the same spec as you (442 with DeDion), but rather than messing about fabricating my own brackets, I bought them pre-made from Darren at GTS, £15 the pair (with Dedion plans included), my time would have cost more than that!

Cheers

Alex
