Id say get a new switch and go from there.

I would find both off the same generation truck to make it less hassle.

Under hood temps bein too hot or fuel line too close to the motor is what causes it. What happens is the fuel gets so hot it boils and turns into a vapor and starves the motor for fuel.

Not on all of em my bronco has the same pattern as the a 435.

Put new rear springs on the bronco, swapped in a 3.00 pumpkin in the rear axle, pulled the front shaft and changed the speedo gear. Next up is to lift it but that can wait for another weekend.

Check the filter if that dont fix it id say vapor lock. The fix for that would be either an electric fuel pump or a higher pressure mechanical pump.

The T18 in my bronco also has a granny so it could be either one 435 will have an aluminum shifter housing and T18 will be all cast iron.

Pull the axle out along with the carrier and mark the bearing caps wich side ya pulled em out of then get a pry bar and pop the old seals out if they dont come that way put somethin through the other tube and smack em out that way. To put em in get a broom handle and stick it through the axle...

Thanks guys. Havent been able to post much cause of work but I try.

Is it just me or do I not see any rear springs.

You can get a new lens for about the cost and hassle of tryin to buff the old one.

Got the other half of the lift kit for the bronco today gonna be puttin that on after I finish the rear axle.

Changed out the rear springs on the bronco next weekend its time for the rear axle. Gonna swap in a 3.00 pumpkin, pull the front shaft and change the speedo gear for milage in the summer then winter the 3.50s will go back in.

Be better to do a 5 speed swap.

I wouldnt recommend draftin becasue its dangerous and it pisses drivers off and ya might end up with a face full of gravel.
