Part XI - how to re-attached hard lines, sources for Belleville Washers, correct assembly order for washers/spacers/etc on upper/lower front suspension, THE definitive discussion about window regulator - where seals go (and where they don’t) - lube points - winder spring - how to insert the regulator - sequence of insertion, Lesson Learned about trusting vs verifying (ref machine shop setting valve lash), dimensions and obstructions for hard wood spacer insert in the bottom of the picture frame, adding a duct fan to fresh air hoses, grounding strap(s), and it’s a tie down point used during shipping not a towing eye.

Part XII - upper and lower door glass stops, applying DEI Heat Shields to Trans Tunnel, importance of cleanliness of regulator spring, Terry’s for long and short PS Rack lines (plan on 3-5 weeks for delivery), orientation of motor mounts (and the challenges of mounting them), installing boot matting and the mat that doesn’t belong on an OTS (lots of photos of original matting), conducting a gas leak test of valves sets, short block → long block, powder coating result,


I really enjoy following your progress Craig. Thanks for taking the time to document your work.

Thanks Dave - I enjoy the reporting nearly as much as the restoring.
I hope the notes and photos help somebody sidestep my errors.


Absolutely they will Craig …I keep reading with interest …… whoever the next custodian ( eventually ) of this beauty is will be able to say with certainty ……this restoration is well documented ….keep it up ……it’s not something that I could do with your same enthusiasm ……Harvey is the same …… it’s terrific to see such dedication


If the engine runs well THEN I’ll sign the oil pan.

HEY!! Just what exactly is this IF SH!T :shocking:

I expect nothing less than :3gears: (but with 5 gears; not just three)


Just wanted to close out the topic I broached in Part XII: finding and using the M12x1.0 tap to prepare the hole in the brake light switch mount to install the Lucas replacement brake light switch (with metric threads) into the mount (with SAE threads).

The tap (and die) arrived on Wednesday (took about a week even using Amazon Prime) and I finally got a chance to use it today.

Very anticlimactic.
It was fussy getting the first threads to be cut aligned - I assume cuz the original SAE- threaded hole was so close in size to the metric tap.
Once properly aligned, it took about 20 seconds to cut the new threads.
The Lucas replacement brake light switch threaded into place without fuss.

If a J-Ler needs the tap to do the above, just let me know.

Where did you get that guy burning rubber in 1st, 2nd and 3rd gear ?

Cool !

I spent some time documenting (with at least the level of detail I am posting my restoration path) the build of my Garaj Mahal on (If you are interested, my thread is Craig's Colorado Car Condo | The Garage Journal – ya gotta subscribe to see photos, but there are no ads bombarding your in-box nor embedded in the site.)

They have a pretty neat compilation of animated emoji’s over there


but little racing dude is my favorite


You can copy the gif image and save it to your computer. Then simply add it to any posts you want!

I’ll be dingle dangled!

Thanks… I always wondered how to do that… :slight_smile:

Thanks Doug


But where did the cool thing come from ?:blush:

Asked, answered…

I had to slow down a bit Paul……

I really had to switch gears today ( :3gears:) and put in a day’s work on finally completing my compressed air distribution system. (After being severely chastised by @Wiggles for the third time, I needed to get off my ass.)

I installed much of the lines in the larger room with a 14 foot ceiling back in May 2022 (after my Jag had been in dry dock for 14 months). I hadn’t planned well and was stymied by the black pipe vertically bolted to the wall with near-zero clearance. That stalled my initial efforts.

I picked up there and today added the zig and zag - hence the step in the first photo.

I was expecting help from three Jaguar stalwarts but @Wiggles and his buddy Dave along with @Jeff_Schroeder got hit with a late spring snow storm. Gotta love Colorado. With their help this whole set of lines would have taken an hour, maybe two. Getting to this step took 2 hours.

The last leg was to run the air line from the corner to the garage door (I want t have the option of extending compressed air outside the garage door. Another coupla hours.

Looks like it would be easy and straight forward but it took multiple repositioning’s of the scissor lift, using foot-long left overs of the wiring for the garage to lash the loose end of the line, using the window sill as a brace, and several trips up and down for forgotten tools or bits. Got some house keeping to take care of that requires the lift.

Still gotta plumb the air lines into the Dirty Room and the small room (both require drilling through walls) but that doesn’t require a scissor lift. Pretty sure I have enough components and hard line.


My garage ( quite small by comparison ) has only 3 outlets which installed prior to the plaster lining going in ! ….I have one connected to a 20 metre reel on the ceiling

That is one of the housekeeping steps I’m gonna try today.
I have a hose reel I intend to attach to the ceiling.
That leg was installed during my initial efforts over a year ago


With my Jag on the lift immediately below where I want to install it – that may hafta wait.

Utek say good idea.


Sure beats my procedure-- long hose attached to compressor, snaked under the lift when it is up.


How many cars do you intend to do in the Garage Mahal? Not just one Series III I hope. I think I have a basket case XK-140 with your name on it.:slightly_smiling_face:.
