Off Set Trailing Arms

Hey out there...
Wanted to get some advice on an area I am currently working on my 1977 rebuild.  I have been contemplating swapping out my OEM trailing arms and replacing them with some remanufactured off-set trailing arms.  My goal is gain some space so that I can run some wider low profile tires on 7x16" wheels.  But as I look closely at the wheel well and frame area...It doesn't seem clear to me that I would gain the advertise 2" additional space.  

So before I dump a grand on the parts…is there someone out there that can tell me if in fact I will or will NOT be able to run wider wheels?  What was your experience on ride performance?  If its all good, any recommendations for a supplier?

Thanks in advance…Ez.

 

there are several articles when i googled offset trailing arms...  but not with the exact answer you were looking for...

i did not read very many... there are dozens and dozens of google links...  

Thanks for the input.  

So does anyone know of a good supplier for off-set trailing arms?
