Ford 7 1/2" I.R.S.

[H-L-Smith]

There are several people in the USA who have, or are, adapting the Thunderbird and Lincoln (similar mechanicals, but lighter aluminum case) IRS system to Locost chassis including the Haynes Roadster. If you have an interest, I can collect some links to their build logs and any discussions of the units accessible on the Internet.

Regards,

Lonnie
