i am finally insured...Hagerty wouldnt insure me because my daily driver is not 20 y/o or newer...went with american collectors instead

[Dieselwrencher]

Man, awesome work! I can't believe I've been missing your build.

[Coboyle04]

well the day has come......it's alive!

keep in mind how quiet this is considering there is nothing beyond the exhaust manifold. we will now be at the exhaust shop on monday.


well crap...does anyone know how to post a video...reply if you want to hear this beast fire up!

we found a problem with the torque converter we ordered from Georand transmission. They didnt send the one we spec'd the new one runs much better and i will have a new video with that one shortly

sorry, i thought you might want that.....they are 16x7

[Coboyle04]

some more delays...the new torque converter is in and running good, was awaiting delivery of a pseed sensor for the tach and trying to find a good place to mount is difficult. we are going to remove the crankshaft pulley and replace it with a new harmonic balancer as found on the 6 cyl's....this will make it easier to adapt and it might smooth out the motor a little bit more.


anyways here are some exhaust pictures from Canby Muffler
the s curve from the turbo to the end of the firewall is double flanged for easy removal in the future for maintinence or repair

[Coboyle04]

more exhaust and a new under sash gauge panel for the boost and pyro as well as some switches, fog, Overdrive, etc

and a few pics after its first bath in about 2 years

[jbclassix]

cant wait to hear how she travels, and mileage! Well done!

[DouglasRaymond]

Cool build, very nice.

[ERASER5]

Could you point in the right direction to look at your engine? I may have candidate for a 4BT, at least I can dream of it.

[Coboyle04]

My machinist found it for me down in california....

[Coboyle04]

Good news....the beast is finally road ready...bad news is im out of town for a week....i will pick it up next wednesday or thursday... ..stay tuned!

[Coboyle04]

I picked it up last week and was so frustrated i nearly thought about selling it!!

The battery was not charging- i found the alternator did not have 12v to the voltage regulator so it wasnt charging, the starter had abad wire crimp that kept popping out and another extremely loose connection.

There is a fuel leak on a vent from the injector pump

the dakota digital tach interface is not working

Pyrometer switch was loose

The heat valve for the AC/heat was installed backwards, the ground for the AC switch was removed.

I have been a little busy and all that is left from this list is the fuel leak and tach issue.

[Coboyle04]

no mileage updates for you yet but maybe by the end of the month.

I still need to tighten some other bolts, install the hitch, charge the AC system, anchor some parts that are vibrating excessively, wire the grid heater, get rear shocks measured, install tow hooks, adjust a couple trim clips, have the doors re-aligned, some paint fixed, tint fixed in 2 windows, install a cage on the trans cooler.

i was also thinking about a trans tempt gauge.

I am also having a hell of a time finding these mirrors. i have found some but the legs are either too short (10") and narrow or way too long.

any help would be greatly appreciated!

I think those are early mirrors. The shorter legs are the ones that are correct for the '72. They tie into the door at the top just below the trim piece and the lower legs are shorter (like the ones on my Sub). They use the same mirror head. PM tkorinek. He probably has either variety and others not mentioned here.
