The headlights are round....
its a 1980 model

Hmmm ... in the US the '79 B310 has round headlights, the 80-81 has square lights.

I like them as they have coil spring rear end like the Datsun Stanza they are exactly the same in suspension components except the front brakes are bigger in the Stanza and the rear diff is bigger in the Stanza which means they bolt into the Sunny direct struts an all as I have...made things easier too

what wheels are you gonna run on this baby to keep it on the tarmac?

15 inch TRX Bluebird wheels with 195/50 tyres........should be heaps

They are a nice fit in the sunny coupe arent they. My sunny coupe race car had an SR20DE in it but I sold the engine and box to a friend due to a planned change to CG13 Micra engine. The gear lever positioning is unfortunate (right throught the stiffening rib at the front of the seats). Did you build up a strengthening plate to fit there?
The best back end to use with the DET is the gazelle H190 rear axle complete. You have to modify the arm connections onto the housing as they misalign by a few mm and put tension on the bushes.

Bolt it in, cut the mounts of the housing and re weld to remove the misalignment. Lower the mount point of the upper arms by 22mm and drop the lower arm front mounts 22mm to lower your roll centre.

Fit good urethane bushes and a panhard rod or watts linkage to get a really good handling rear end
