Definitely more work than is involved with the fuel pump upgrade this thread covers. Although an '89 TC would only involve physical modifications to mount the tank (including fuel line reroute) and the '90+ pump/sending unit electrical connector.
Correct, the resistance range runs opposite for '90+ compared to '89-.
Also for '88- digidash the high resistance value is something like 220 ohms instead of 160 for '89 TC and all '90+.

From that post:
Based on EVTM for '89 CV/MGM and '91 CV/MGM and some prior research
For Analog clusters on '89 and down panthers (excluding '89 TC):
Low fuel = high resistance = 60-86 ohms
Full fuel = low resistance = 8-12 ohms.
For all clusters on '90+ panthers (including '89 TC):
Empty = 15 ohms
Full = 160 ohms
IIRC, '88 and down TC with digital cluster is something like:
Empty is about 15-20 ohms
Full is about 220ish ohms
