This is the 1/24 Hasegawa 510 4-door kit(JDM). I'm building it to clone my friend's 1972 4-door 510 that he set up for track events. Here's a 1:1 pic

It has a Rebello built KA24E with a EFI quad-throttle body induction and SDS fuel control. 16" Panasports and 4-wheel Wilwood discs.
My first time with DetailMaster photoetch parts!!!
Onto the model. The closest thing to Panasports, Rs Watanabes and I couldn't help but keep the Brembo calipers/discs! Center section is painted steel, lip is chrome silver.

Dan's car has a battery where the rear seat used to be, aluminum door panels and a full roll cage.

Here's my attempt to build the battery from the above photo!

I used photoetched battery clamps for the ground and + cables. It was hard getting that clamp around the cable! Grounding cable is painted tape textured with Xacto grip. Sewing pins to make (4) posts and styrene tabs for the securing battery.
Now for the cage and seats...

seats

These are seats are from the Focus WRC kit and I love them because they match the 1:1 driver's seat and it even has that Sparco I.D. decal on the side!!
Battery cable to engine bay: Goes from battery along passenger seat through firewall, and has (3) sheet metal screws holding it down. Seeen bottom right of pic:

The tranny tunnel is modified(covered in sheetmetal/electrical tape!) to make room for the KA24. Check out the "brushed" aluminum door panels.

Here is the main hoop with modifed harness bar. The hoop is from the BRE kit, but I had make the harness bar, and remaining cage from rod.The harness attachments are the #tabs from the sprue!

Seat belts!! This was so much fun, but really tough for me. If you look closely you'll see the bolts holding down the belts to the floor

Front view of just lap belts:

Got the shoulder belts mounted to the harness bar!! mounted the clips so they look like a single bolt is holding them in place. Dan's gonna love it!

Here you can see how the rear bars go through the back panel to tie into the rear struts.

Finally! Tell me if I threaded the belts correctly, I know I lost 1 clip!

Painted rear bars black

SOme underbody detail in progress

Some fit mock-ups

door panel paint rough(brushed aluminum?
See the door panel, where can I get some scale door handles like that??That's my little bro in the pic
Well, that's where I am. It was a blast doing the interior, but some things I'm concerned/need help with:
I-'m not happy with the door panels, they look too "brushed".
-The belts are alright, I used the material that came packaged, but -I've seen "weaved" pattern belts in others projects.
-Is the battery cheesy, my bro said the the little bar code I put was way out of scale, oh well.
1)How do I add the nerfs to the roll bar? Heat shrink tubing?
2) How did anyone make the front half of the cage, so that it matches the windshield width, etc.
The roadster is on the backburner and I need to finish this 510 by February!
Comments and pointers much appreciated
