What the heck is going on here?!

Never understood the attraction of these tubular uca's.
Every story has been a nightmare, ie snapping,driving into ditches ect.
And now you have to grind away for them to fit ?
No thanks, not for me, I'll stick to factory here.
Just cant see them giving a 40 yr old car that much advantage.

Unless they told you some modifications were necessary, I would send them back.
