Speedo Adapter

[63BlueMGB]

Hello,

I I have a non-WC T-5 out of a 1990 mustang, I had to order a new speedo adapter for the transmission and gear, However, I do not have the adapter screw to secure the speedo adapter to the transmission, Does anybody know what size the screw is, i cannot find any info on the internet and I am hoping somebody knows out there. Thanks in advacne for any help or info!

1990 Mustang should have a WC xsmn.......
I have a WC T5 Camaro xsmn that uses a M6 x 1 screw for the speedo adapter mount - I assume that Ford is the same.

Edit: forgot to mention that screw is 15mm in length
