Re: searching for 78 to 79 LTD II
I'm not exacvtly sure what you are chasing but it doesn't sound like an 78 -79 LTD which is designated the P6 LTD. I've owned both a 78 P6 and 79 P6 Towncars.
The P6 never came out with a 302, and I am pretty sure thet never came out with a sports pack or stripes.
I'm sure you will hear from Paull in a little while who is an authority on the P6 and has one or two of each version of the P6.
