72 burb 1/2 to 3/4 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

qksilver · 03-20-2006, 11:11 PM

Just brought back a 3/4 LWB truck frame from Bills Bowtie. Took the senic route what a ride! 9% grade, 11% grade..........LOL
The questions, I am tired of doing frame swaps.
I want to convert/pervert one of my 1/2 72 burbs into a 3/4 2 wheel drive.
Are the frames the same, as far as strength?
Are the engine crossmembers the same? So I can swap just the suspension not the crossmember
The 3/4 truck frame is leaf , the burb coil. I am going to swap spring perches on to the coil frame. I measured and it will work.
Are the 1/2 burb rear crossmembers strong enough? or do I need to find burb 3/4 rear crossmembers for leaves( so they will work with the frame mounted tank).
Are 1/2 and 3/4 steering boxes the same?
I am building this to replace my 99 BB 3/4 burb as a tow vehicle so I want to make sure it is strong enough ( for the rear spring perches)
Any pix of a leaf spring 3/4 burb would be great.

I'm pretty sure that the 3/4 ton trucks had some reenforcement... but only on the coil spring frames.
So if you were to do leafs, the frames would be the same.

Thanks, I looked at my longhorn but the gas tank part concerns me.......

I towed with a 1/2 burb with bags on the back for almost 2 years. Probably towed at least 40 vehicles. I will have a 354 dana coil spring rear from a 3/4 ton in a week or so.
