Mercury Grand Marquis donor car

Greetings folks, been a while since I've been active... I'm in my 40's and my hobby experience over the last decade has slowed down with family life leading to home improvement and the fact I just don't have a garage at home, which I may finally be resolving this year. But I have kids age 12 and 13, and I'm thinking about the not-too-distant future when they reach driving age.

So I have a 2000 Grand Marquis that I inherited from my grandfather who has passed, and which I've kept as a backup car. Used it way more than intended over the last few months after an accident totaled my truck, then a month after getting a new replacement truck another accident put that one in the body shop for a month. Come to find out, in spite of fairly low mileage (75,000) the GM has some issues popping up (had to replace windshield wipers, speedometer quit..)

Anyway, thinking about the kids, my daughter is a bit of an Elvira fan. So I got to thinking, what if I found a decent '58-60 T-bird body and used the Grand Marquis mechanicals to give her something attractive and the idea being I involve the kids in the project. I've been talking about having the GM go to my son, none of the kids really like it...

Anyway, I've always been much more focused on '55 Ford/Mercury, I was wondering if anyone had opinions or experience whether the '58 T-bird/grand marquis combo would work well or even better if there's any similar projects out there with pics.

The Grand Marquis & Crown Victoria platform has a wide front track and works well in 50's Ford trucks check out these videos This forum would probably know best about the swap you have in mind.

Its not a TBird build, but there are also at least two very comprehensive build threads on the internet about using the Crown Vic chassis and a mid sixties Ford pickup truck body.

If you compare specs, the Crown Vic and the mid sixties pickup have a very similar wheelbase (114.7" vs. 115"), while the Tbird has about 2.5" shorter wheelbase. That may be the big challenge if you want to use the entire frame, suspension, steering, etc.

I've seen the truck swaps, but this being something I'm considering for my daughter to get her into cars by way of her interest in Elvira, the second gen T-bird part of the project is pretty key to the plan. I am pretty heavily leaning towards hardtop rather than looking to pay the premium for the more desirable convertible, and I don't need this to be a simple matter of bolting a body onto a rolling frame.

If I recall I found the T-bird wheelbase is 113". I'll figure something out, it will be interesting.

Use T-Bird frame, remove front crossmember, bolt aluminum front cradle from GM, complete with suspension, engine, etc, in it's place. Install rear end ***'y from GM, and driveshaft. Rock an Roll. YMMV
As to the width difference between early Tbird, and late GM, I dunno.

I think that's kind of why I brought the question here... My world has all been '55-6 FoMoCo and I only generally know enough about second generation T-bird to know it's unibody, so I knew it might not even take the full body frame easily.

For that matter I don't know the t-bird weak spots, or maybe I can land a decent body and drop a 390 in that I have already. If I did that, maybe I'd do a frame swap with a truck for my son.

All brainstorming for now.
