Alternatives To Art Morrison Full-frames

[hannes_slanec]

If the topic comes to my Impala and the subframe under it (which I would like to replace since I go with an 572 in my convertible 68 Imp)., people border me with that bloody subframe-connectors.

But I have a full length frame in the Impala and have to replace the entire frame.
Every company I brows for subframes also only got that front frames, back-halfs or connectors.

Are there any alternatives to Art Morrisons frames or is he the only one producing such full-legth frames?
