[HPCOBRA]

I have been nursing my build along for several years. Due to family illness and the loss of my dad and mom the last year has seen no Cobra work. I am about to get back to it. The kit was originally assembled back in 1995 and after 75 miles and a minor accident it was put in storage. I acquired it about 4 years ago and basically disassembled it and almost started at scratch. Things were just not done right with the original build. I recently realized that the rear axle pumpkin is off center about 1 inch. The axle tubes were cut to put the wheels in line but as mentioned the pumpkin is off center which puts a little angle to the drive shaft. Has anybody experienced the same issue? Will the universals operate okay with no vibration? Should I use constant velocity joints instead?
Thanks for any help
