we are allowed to run tractor tires legally up to 35 mpg, i have had them to 70 mph coming back from a run. the down side is the cornering is dangerous due to the soft sidewalls and you can wear the rubber down in quite short order at those speeds due to the heat generated.
the 70 ragtop, 73/74 series and of course 75 series pickups all have fold down windscreens. the 70 ragtop is the only unit with the factory wind screen retainers and the double folding wiper arms.
the 70 ragtop is the only unit that has the 2 piece doors front and rear. these doors can be unbolted to make factory 1/2 doors front and rear.
this particular 70 ragtop has the factory elec locking diffs, factory snorkel and power steering and AC, all which are very rare on the 70 ragtop SWB.
the ragtop, unlike the 73/74 series never had the option for a removable hardtop so i took the hard top from the 73/74 series and cut it to fit my truck. the finished result was clean and ALMOST looks as if it came from the factory.
if you are interested, here is a link to the conversion:

the engine is the 5 cyl PZ coupled with the R141 when i removed the R151. the gearing in the R141 is identical to the H41 where as the R151 was a nice highway tranny. I have had a "in the box" turbo sitting here for this truck since i bought it but i have had no reason to install it. happily, the muffler is on the way out so maybe i will stick it on when i change the system.
cheers and thanks for the compliment.
