Surfdog’s 71 240

Good news the diff rings on both my 240 and Datsun are 3.53 ( what I wanted) so I have two good diffs. (One spare)

Edit: it’s a 3.3 diff. A bit tall, but since I’m running a torquey 3.0l setup on a still very light rig (hoping to keep her under 2000 lbs) we should be okay. I hope the maxima diff is a 3.5 in case we want to build up a “swap in” sprinter diff for shorter track races. I don’t mind refurbing a second diff, but those Quaife center sections are a bit pricey. ($1200 ish)

The maxima 5 speed is also a direct swap spare. (Same gear ratios) Sweet!

This $1,000 honey is a gold mine!

My 240 motor internals look great. (Though I tossed the crank and 2.4l block for scrap). I’ll use the head.

My 240 5 speed looks great. I will rebuild with new synchros but gears look good.

Getting the shift fork actuator rod out can be a bitch unless you cheat and drill out the case. Then you can brace the shift fork and bang out the retaining pin/bolt from outside. Tap in a grub screw to seal up the hole and your good!!
