Hi Nick
Thanks for the response. To my logic I think the same way you do that the right
side of the car ( passenger side) should have the right hand thread. What
troubles
me is that my car had two right handers after I replaced the one on the right
side. that tells me it used to be a left hand thread.
As far as the upper a frames go there is only about a .100 inch offset in them
when measured on a surface plate with a height gauge.
I will call Lenny Renkenberger in Maryland (Autosport-Coachworks ) today and get
his input. He has put a great number of TVR's together.
