1969 Road Runner by Jo-han, hardtop to convertible conversion.

Recommended Posts

Posted (edited)

I bought a couple Jo-han 1969 Road Runners off eBay in recent weeks. This one in particular was more of a glue bomb than the other. So much glue was used to secure the glass that it melted the roof. I figured it would be a prime candidate for a convertible conversion. I picked up the AMT GTX convertible from Hobby Lobby, they conveniently reopened last week!

I started by cutting out the tulip panel including tops of the quarter panels around the rear section of the interior.

I had to narrow it a little bit at one of the natural seams. Then re-contour to match the shape of the deck lid.

I removed the windshield surround from the GTX including the tops of the fenders and doors for added strength. Plus I kinda like the cowl shape better than Jo-han’s

There are couple spots to sand, but it’s pretty much were I want it.

I spent six hours, in a model car hang out online last night,  fitting the interior. I will post those pictures a little bit later.

I'm not generally a fan of convertibles, but this is nice work, and it's interesting to watch. Drive on! B)

Great looking work on this conversion. In primer you would never know what all had been done. I like your idea of going a little further into the body to make your cuts, I can see where that would add a lot of much needed strength.

So far so good.

 

You've given me an idea how to do my old car . I have a spare damaged Johan 1969 GTX body and a AMT GTX vert kit.

 

BUT, just an FYI. On Mopar  B body convertibles there are no visible seams on the rear dutchman panel like a hardtop has

This 69 Hemi RR convertible looks just like the one in the sales catalog.

Nice save! I've got the Amt prostreet 1989 or 90 issue it was a glue bomb and the top was ruined also... My cousin built it back in the day... then it went in his attic for 25 years or so... I got it now and have been slowly redoing it...

Thanks everyone! 
 

Here is some of the interior modifications.

I had to shave off the back and lower edge of the door panels to move them inboard a little bit more. Especially towards the back.

It was the only way to fit it between the doors of the body, but that also closed up the gap between the convertible panels and the rear seat.

Unfortunately the convertible boot does not cover the area where the convertible top folds down into. I guess technically it should be wider. And then the arms extended a little further toward the doors.

Think I’m going to need more reference material with that. In the meantime, I’m considering an up top For the convertible.

I had to shave off very little on the side of the dashboard to bring the door panels in slightly.

overall it doesn’t look too bad, save for the convertible boot.

Comments and suggestions very welcome. If you have any good pictures of the top up or convertible boot on one of these 68-70 B-bodies, I would love to see them!

I assume due to the pkg tray area the boot can not move any farther forward ?

 

On the 1/1 car the boot fits up nice and snug to the back edge of the rear seat

You are correct. And that’s my problem here right now. Follows the contour of the rear edge perfectly. But I would guess the whole thing needs to be wider.

From this picture, it looks like you just need to add some to the boot, as it does not go all the way to the seat.

The MPC 1969 Barracuda has them . They were added during the c.1989 reissue ; they're not in the original 'annual' kit .

There is a metal filler panel right behind the seat. its maybe 5 or 6" wide at the most. the forward edge of the vinyl boot clips into the backside of the filler

Seems to me someone had a corrected resin boot for these but I can't find the pic.

Great looking project, Mr G! Getting me closer to digging out and finishing my '70 johan 'bird to R/R conversion :P
