Chris, Unfortunately the 1970 Master Parts Catalog does not list a part number for the transmission lines. The book indicates that replacement lines are to be fabricated on site using a roll of bulk tubing. However.... I believe that the trans cooler lines will be the same for the Imperial and the 300. Probably others, too. I have few sets of lines from mid-60s Mopars and I'll compare them to those on my 70 Imperial. I won't have any answer until next week, though.

Date: Tue, 09 Mar 2004 17:46:44 +0000 Reply-To: mailing-list@xxxxxxxxxxxxxxxx Hey Everyone, I'm in search of some information about transmission cooler lines. Are 300's and Imperials the same dimensions for trans. cooler lines? I know that they look somewhat similar; but, I need some help. The previous owner of my 70 Imp damaged the cooler lines when he rebuilt the engine...so they're presently jimmy rigged w/ rubber lines in two different sections. I called Classic Tube and they can make a set for a 70 Chrysler 300 (stainless for $80); but don't have the neccessary info to build them for an Imperial. If anyone knows please help me out. I can bend my own; but, I prefer to have them professionally done. Thanks! chris graber 1970 Imperial LeBaron 4dr.
