400i front suspension parts

Yes, most of the parts are common with the models you mention and also Maserati's of the same period and earlier. There is an ebay vendor that sells a complete set at quite an attractive price if you need all or most parts.

Rutlands will furnish you a complete list of parts, if you ask them. They are very accomodating folks. Also, go to the 308 forum..Birdman (and a couple of others) has documented the parts and procedure most thoroughly and perfectly. I think that you will find these quite helpful. Jq.
