Hello.

I need an unusual information about an Alfa Spider.

I am dismantling the suspension and I want to use new bolts.

Is there anybody who knows which is the nominal diameter (size) an pitch (I suppose that it is a fine thread pitch) for the nuts marked in red? (upper wishbone to the body an to the control arm).

These are the only ones in the car and I am not close to it.

Thanks in advance

#1 is a 10X1X50
#16 is a 10X1
#12 is 16X1.5X74
#15 is a 16X1.5

Numbers 1 and 12 are special bolts that are not threaded all the way. Either reuse the old ones or order replacements from Alfa. You may be able to source #1, but #12 will be difficult.

Thanks a lot.

#12 is 12X1.5X74 I assume that is 16x1.5x74

Bolts are very difficult to get. I was thinking in reuse bolts and use new "nylon nuts" (I don´t know the name "autoblocantes in spanish", nuts with a nylon insert) in the required grade.

Also, the nuts are not usual. This pitch is fine and the normal is the coarse thread.
