Default Upper A arm offset cross shaft

Noticed on disassembly that the driver side upper A arm had about an inch worth of shims, when the passenger only had about 1/8" one side and none in the other. My question to You guys Do I go with offset cross shaft on both sides? Or since the passenger side did not seem to need it Would it be wrong if I install it there just in case? It would be very hard to install after I put everything together. But I want to make sure that if there and not needed it won't hurt either..
Thanks for any help..

I'd check the frame before deciding what to do. A significant disparity in the numer of shims from one side to the other is often a sign something's not right.

When I got the car the front crossmember was cracked, and the a arm bushings were shot, The frame has been welded and I am in the process of installing new bushings and refreshing the front end. The works 550 coils bilstein shocks, motor mounts etc. Hopefully there is no actual problems with the frame being bent. Myself and a friend both look at it and mesured and there is barely indication of that.

Besides checking the frame for overall squareness, did you check between upper CA towers as well as between lower CA bolt centerlines?

welding, all by itself can make metal parts move a lot.

with that said, as long as it aligns right, is square and doesn't make any creaking/popping sounds - you're golden. Given today's standards, that would be terrible fit - back in the day, it really wasn't that big of a deal - and still isn't other than aesthetic

Could not get these measurements now. The whole front end is off the car.
I am starting to put things back on the car the next couple of weeks that is why I want to get the offset cross shafts on now if needed.

I hope I am golden! The frame was gasseted and seems square at this point. Thanks
