If we’re going to wallow in nostalgia, and it seems required for this edition of the NBA Finals, let’s do it right. At least in Los Angeles.

Let’s open up the “fabulous” Forum in Inglewood for at least one of the Lakers’ road games with the Boston Celtics.

Let fans return to the true home of the franchise, the quasi-garish faux-Roman building over there on Manchester and Prairie. Let them sit in there and cheer on the Lakers via big-screen TV. If the Forum has one of those, of course.

The Forum was the site of a bunch of key moments in the history of the Lakers and Celtics. From Game 7 of the 1969 Finals, when owner Jack Kent Cooke put balloons up in the rafters so fans could celebrate the inevitable victory to come. (Those balloons may still be up there.) To Game 7 of the 1987 Finals, when the Lakers closed out the Celtics in the last title game involving these two storied franchises.

Here’s what the Lakers do: They arrange with the church that now owns the site to rent out the place. Maybe for Game 2 on Sunday?

Send over some old maintenance guy to put down the floor the Lakers used, put up the baskets. Make it look as much as possible like it did during the 23 seasons (1967-1999) the Lakers played there. Bring over the Laker Girls. Prop up a Nicholson mannekin at courtside.

Have PA legend Lawrence Tanter sit at the scorer’s table and announce baskets, fouls and substitutions just like he would if it were a home game.

Open up the old Lakers locker room for fans to go mill around. Open some concession stands. Open the doors to the old Forum club, and let fans look at where Jerry Buss used to hold court after home games.

Bring in old Lakers from the Showtime era, or earlier. Byron Scott is free. James Worthy ought to be available. Michael Cooper could drop on over. Let them sign autographs on the concourse, or even on the court before/after the game.

Sell tickets for a nominal fee (to go to the church).

The Forum is the real home of the Lakers. I know they have won three titles since the move to Staples (1999-present), and I know they did seven seasons in the Sports Arena … but the Forum is where the Lakers really became “the Lakers.”

(They aren’t even the primary tenant in Staples; the Kings are.)

We could do something like this in Boston, too … except the dopes there tore down legendary Boston Garden.

How hard would this be? And it would be fun. If the Dodgers could get 115,000 people to the Coliseum for an exhibition game, couldn’t the Lakers draw 17,505 (remember that number, you Chick Hearn fans?) to sit among other fans and cheer on and remember the good old days at the funky old building?

I might have suggested going back to the Sports Arena, but it’s too nasty. And, the Lakers never won a title there. As opposed to the six then won while based in Inglewood.

Do it Sunday, after the church folks have gone home.

Or how about Game 6, on June 16? Make that the Forum night. This would work. I’m sure of it. We’re all thinking about Memories of Things Past. Let’s go have another look at the Forum, before it falls down or paved over for a bigger parking lot. I miss the place.
