Hello, Mick,

You appear to be well up on things Cadillac, but some months back, when I was putting my 500/TH400 together, Techinspector 1 and Stu Cool put me onto some Cadillac sites that have been very helpful:

<http://cad500parts.com>
<forums.500cid.com>
<http://www.cadillacpower.com/forum/index.php>
<http://www.gmcws.org/tech/caddy_swap.pdf>

Maybe there will be something there you can use.

You will find the most knowledgable and accommodating people anywhere in this group. Welcome!

Jim
