Here is the deal. I have the original bolts to mount the spare. However, they are for the original tire size, which I no longer have. I'm looking for a bolt with the same thread...just a lot longer so I can make it work.
Is there anything close that will work with the particular threads in the hood?
Trying to figure a way to secure the spare on the hood. Original bolts are too short.1971 Series IIa Hybrid: 2.5L MILSPEC 5-Main Bearing Engine|Turner Engineering Performance Head w/ oversized hardened steel valves & phase shift/increased lift cam|LT77 Tranny/LT230 Transfer Case|11mm Ignition Wires/Super Coil|Jacobs Ignition/Petronix Ignitor|D90 Axles|Galvy Frame|Old Man Emu Coils|Cust Rear/Side Fuel Tanks|Cust Drive Shafts|Comment

Originally posted by TedWNo one stocks a longer bolt so I drilled and tapped for a larger (and longer) bolt. Works swell, except that the head size is different - not a big deal, in any case.1971 Series IIa Hybrid: 2.5L MILSPEC 5-Main Bearing Engine|Turner Engineering Performance Head w/ oversized hardened steel valves & phase shift/increased lift cam|LT77 Tranny/LT230 Transfer Case|11mm Ignition Wires/Super Coil|Jacobs Ignition/Petronix Ignitor|D90 Axles|Galvy Frame|Old Man Emu Coils|Cust Rear/Side Fuel Tanks|Cust Drive Shafts|Comment
