Taper on Sierra Uprights, Bottom Joint

[Rosco]

I need to deepen the tapered hole on the bottom of my sierra uprights to get more engagement with the stud on the ball joint when I put the self looking nut on.

Does anyone know where I can get the correct sized taper reamer or similar?

Or does anyone know what size the taper is?

Cheers,

Rosco.....

I think I have the info you need.... But..... It's on a DVD I lent to a freind an dhe's up in York
I'm sure on the DVD ' A Race Car Is Born' he mentions it. I'll have a word tomorrow with him and see if he can do some homework for you

Just put my copy of a race car is born in the dvd drive.  No mention of taper sizes when he's fitting the front suspension.
