I did go with the radiator that's in there because it fits perfectly behind the large intercooler.
Also my radiator is berried behind a few things like intercooler, transmission cooler, engine oil cooler, power steering cooler and the Ac condenser.
I figured I should give the engine the best...
The om617 is a really good engine, but not for a 60 or an 80 LC.
I do have a 40 series with an OM617 engine and an H55 in it and it's pretty nice to drive.
Not going to win any races with it, but it will get to where I need to go.
You should look into OM606 a bit deeper before you rule it out as a viable candidate.
With an upgraded injector pump ( 7.5mm ) and a larger turbo it can produce close to 500hp and more than enough torque to move the 80s LC
and still get way better gas mileage than any gas engine.
Just my $.02
You'll be perfectly fine driving it to the shop.
Guys brake these on the trails and drive home with front wheel drive only in 4 wheel Hi. One of the big advantage of having an FF rear axle.
The axle only drives the wheels, does not carry any weight in the FF.
I'd go with 6061 T5 or T6 aluminum ( aluminium on the other side of the pond ), good weldability and medium to high strength, depending on heat treatment.
On the thickness, if you could bend a couple of ribs into the long flat sides 2mm should be ok, if no ribs then go with 3mm.
I'd say that the White / Black ground, Red / Green 12v, the other Red / ( can't see the color ) is back light for the switch ?
and the two light green is the antenna motor.
You should be able to test this with a test light or a DVM.
I'd start by reattaching the loose ground terminal to the engine block, and cleaning the battery terminals and the battery posts.
Take the wire out of the positive battery terminal and clean that as well, as for your fuisble links (according to your firs picture )
looks like they're just got...
