Looks to be the same front suspension as my 74 HILUX in the pics which means you will be able to get some rebuild pieces for it still. The 4 wheel drums actually stop the little trucks quite nicely as Phil stated. The problem is finding the drums now, I have found lots of listings for them but I can't find anyone who actually has stock of them. If anyone in SSM land could help me out on that I would apreciate it.
The late 74 -78 trucks had disc brakes you could swap onto your spindles. 74 was the switchover year for some stuff on the HILUX if you're looking for parts. The late 74 trucks had a 20r and disc brakes where mine is an early 74 and it had an 18r and 4 wheel drums. My 74 has a bastardized 22r swap in it thanks to the previous owner but it gets the job done for now.
The bigest hickup you will find in swaping a 20/22r into the earlier truck is the oilpan. The HILUX has the steering linkage behind the front crossmember which causes a problem with the rear sump pans that most of the r series motors came with. The HILUXpan is a discontinued item form toyota as well. If you can find one at the wreckers be sure to grab it. The other option which is what I choose is to get a 82-85 toyota celica oil pan and pickup. It is a front sump pan as well because those celicas had a rear mounted rack and pinion steering setup. I got mine thru LC engineering as they had it in stock.I would have had to pay upfront and wait for overseas shipping via boat if I had ordered it thru toyota.
A later model 5 gear trans with a mechanical speedo will hookup to the earlier trucks speedometer cable which is a plus. My truck has had the crossmember modded(poorly, I might add) by the previous owner to accept the later model trans. I'm not sure if you could use the crossmember setup from a 20r HILUX or not as I can't find a truck like that to look at around here. I would imagine that you probably could, I'm not sure what the differances are between the 4 and 5 speed transmissions are physicaly.
The earlier trucks use a bellcrank throttle linkage whick is junk in my opinion. If you switch to a later model motor with a carb you can use a cable and pedal assy from an 84-88 truck with a little fabrication. LC still lists a header for the HILUX with a 20r and you can get all kinds of go fast goodies for those motors as well. I'm not sure how tough the rear axles are in these trucks. I'm gonna have to look into that one I guess. I was thinking a narrowed later model axle might be a good choice because you can get a locker for it and it would keep the bolt pattern as well.
It would be a bitch to lay the front of one of these things out with the stock crossmember, thats for sure. They need about a 1.5" z to get the front crossmember even with the bottom of the frame rails which is not really an issue. The real trouble is that the steering column is attached directly to the steering box. This means modifying the column with u joints and extra steering shaft to get it all hooked back up after. I found some exploded diagrams of the coloum and it looks possible, I'm just haven't done it myself yet tho.
They are simply wired little trucks with very spartan interiors from the factory. The little heater box in my 74 makes good heat and takes up little space as well. Mine has CRX buckets swapped into it from the previous owner, they seem to fit in pretty easy. There is still a steering wheel adapter listed through Grant if you want to swap out the stock school bus wheel. You can use the gaskets from a VW bus to seal in the windshield and backlite if your original gaskets are trashed.
Yours looks pretty good in the pics, for the money I say do it. Just poke away at it in your spare time and don't worry about making a daily out of it and you will be fine. I enjoy working on mine alot, its a real challenge finding out info on it but I kinda like it. Hope that you got some info out of my little novel anyways, hit me back if you need anymore questions and I'll see if I can help. Keep your eyes open for parts for me when you're roaming the wreckers as well, it would be apreciated.
