The cars didn't really start to appreciate until Gone In 60 Seconds was released in 99'. 
I think Randy will remember the rusted out 67' GT350 hulk that was turned into a pro touring car. ( White with blue Le Mans stripes. It's the real deal.
The story I recall the cost at the time far exceeded the 67 GT350 value at the time.  ( late 80s, early 90s.)
Yes, most of us these days would look at it as sacrilege but there were plenty of cars in the 3-5K range in the early 80s in So Ca.

Thank you for the heads up. I was concerned that may be an issue.  I had planned on pulling it to change from the 389s that were supposed to be 350s to 318s I have.  Joy. Does anyone have a cover if I need one? I might as well line up my ducks in a row so this doesn't turn into a 1,000.00 project.

If you're Henry or can get a message to him I would appreciate it.

I ordered some replacement inserts for my 1/4, 1/2 and 3/8 kits. I looked at their head bolt thread restoration kit for the Toyota 1AZFe and 2AZfe. It is recommended by Toyota itself. It says much about their product.

I'm glad you had success with my recommendation.  Nothing worse than doing them in the car in a unibody car.

I was talking to my neighbor who was a Millwright in a refinery. He mentioned they had an issue with some of the early products from Time-sert. He was also the one who turned me onto the Time-sert. He told me that they had changed some materials and processes at some juncture. Helicoils serve their purpose but I have seen many fail in soft metals. I loved the self-setting shoulder with the insert. I think they were the best choice for the rocker stand repair.
As they say. There is always a proper tool for a particular application.

Congratulations.  I can fly for 9 more years before the FAA yanks my ticket.  My father worked in oil industry as a field electrician until he was 75. ( He was the guy that cleaned up all the crappy union electricians mistakes)  Be sure you stay active. You'll go down hill fast if you don't.
ENJOY!

Yes, ford used a "Proporting valve" AKA residual valve in the rear from the factory. It holds 10 PSI to the rear brakes.

A Time-sert is EXACTLY what you want to use. The poster above has never used one I would gather. They come in two different varieties.
There is the regular time-sert and a the one designed to repair a hole that has already been repaired.
They work flawlessly. They have a shoulder that will sit flush with the deck. They are also self-locking. If you want pictures of what comes in the set I'd be glad to post them for you. I had to use the over-sized Time-sert for the rocker arm pads. Edelbrock uses a crappy weak Helicoil in the aluminum heads and they simply don't hold well.
Spend your money on the standard Time-sert kit.  There is also a pilot tool that guides the drill and the tap.
