You can (and some people have) swapped bodies between a 77 and an 02-up CV. It’s just like the Ford Ranger, except with the Ranger, they changed one bolt location. They didn’t change anything on the CV.

Is wheelbase a thing?

1973-78 LTD wheelbase: 121"

1977-79 LTD II wheelbase: 117.9"

1979-91 LTD/Crown Victoria wheelbase: 114.3"

1992-09 Crown Victoria wheelbase: 114.6"

Kind of casts a doubt on the accuracy of the rest of your information. Or I guess those body swaps looked pretty funny with the wheels hitting the wheel wells, huh?

so the rules are still the same. You fail again.

Well you fail math!

The 73-78 LTD isn’t the same chassis as the Panther platform, though the Panther chassis was developed from it. The 77 LTD II is what the CV came from.

Moving the axle back or forth three inches (especially on a body on frame car) isn’t significant at all. The classic XJ, for example, was available in two wheelbases - doesn’t make them different cars. The Lincoln Town Car, which we all agree is the same car, is available in a 117.7 inch wheelbase and a 123.7 inch wheelbase. Still the same crap chassis underneath, and the body of a 1982 Town Car will still drop right onto a 2005-up Town Car SWB chassis (this has been done recently by a couple of crazy Dallas hotrodders with access to flooded Katrina cars and a bent-frame hot-rodded Town Car). So you fail again.
