That is not an F.5, the F.5 has the oil filter in the same place as a 2F, just forward of the distributor, this is used for the newer full flow oil filtration system incorporated in the 2F engine. I can't see the filter. In fact all I see is an oil fill tube, something that was also gone on the F155 engine, maybe even the F145 engine. I know mine is blanked off, as in never even cast into the engine. Mine is a 4/73 F engine, an F155, the F.5 was also labeled an F155 but came out in late 1973 I believe, along with a 4speed for a few months until the 2F and 4 speed combo replaced it in 1975. Oil fill cap on the valve cover replaced the tube on the side of the block.
You have an earlier vac advance distributor, something anyone could have swapped in. I don't see the factory lift hooks though and no evidence of factory smog components. Again not unheard of, easily de-smogged, but the other odd thing is that the main pulley only has one groove. A 1974 would have a two groove main and two groove waterpump pulley to drive the smog pump mounted where the forward engine chain hooked up in your photo. That is a smogged 1974 air cleaner assembly though. Thats also a later plastic fan for the non-clutched waterpump. Someone has also butchered the factory fuel lines and deleted the factory mechanical fuel pump in favor of electric I assume. Seems this engine was messed with a bit at some point, no an original block for a US spec 1974, maybe this came out of central america long ago, could explain some differences, not sure.
You probably do have the stock 4speed trans. The first 4 speeds still used the clunky rattling shift linkage found on the 3speeds for the transfer case. They also did have the lower low range of the 3speed transfer, and these were the true conversion tranny, the source of the gear we all use to swap 4speeds onto 3speed transfers. Should be a good tranny settup.
As for windshield frames, why do you think you need a different one. Up until 1975 the windshield frame and tub was designed to accept the hard top or FST right off the line. The footman loops were present on them no matter what. The row of threaded holes in the top of the windshield frame was for bolting on the forward canvas rail. Footman loops in the back and then there should be 4 holes in the lip of the tub on each side above the wheel well. The single stud twist locks used on the jump seat straps mount there and hold the sides of the canvas down. One right behind the front doors for the stationary piece of canvas and three for the roll up sides. If you get the factory twistlocks and grommets and do all the factory attachments the top stays pretty good.
