TR2/3/3A TR3 body back on chassis for trial fit

I put the body back on the chassis and have a few question about the spacers. How accurate is the book with there recommendations for the spacers? I saved all the original spacers and it is nothing like what the book says. No way can I use 4 square spacers per pad. It looks like mine had 3 in the front and 2 in the back. And the spacers with the aluminum washers no way to use the thick and thin pad in the front, and two thin on the back. Should work fine if I reverse it.

Rear shock gap between body and mount. R side 1/4" R side 3/8" Seems kind of tight.

Has any body installed some rubber between the floor and the outer frame rail? The book shows none, but mine is very tight. I think it would help.

Keith-

When I pulled the body on my 3A, there was rubber on the outer frame rail. I think I took a picture if you want a reference shot.

Keith - looking good. Nice to see somebody a few steps ahead of me to run into the problems before me :yesnod: Btw... What color is that?

Keith: I assume that you have this diagram. It's from the parts catalog.

I wanted to be sure that you were aware that there were rubber strips in several areas in addition to the thick and thin pads and aluminum spacer things. Over the years I have been involved with dismantling quite a few TR's and the number of spacers, pads, etc. has never been the same. This makes sense. The pads shown are for illustration only and to provide a starting point. These cars had lots of variations and these spacers were a way to make up for the variation in fit between the body shell and chassis. It will take some fiddling to get it right. Even when you think everything is perfect and you start to tighten the bolts, the pads will compress and you will see things like doors binding and changes in the gaps at the "A" and "B" post area. Don't get stressed if that happens. Just let things settle over night and then you may have to add or subtract a pad or two.

Something that might not be obvious, is to have the car set up on the wheels and tires with correct tire pressure and on a level garage floor. We used an inexpensive laser level set up on a tripod and panned along the rockers (for example)to get some reference points. Remember when people used loose-leaf paper? Remember those little donuts that were used to repair the torn out paper holes. Well, they make excellent laser targets! We numbered and stuck them on at strategic places and then recorded the height from the floor and the distance from an arbitrary "construction line" we drew on the garage floor. We started with the off side and then repeated this process on the near side. Then we repeated this on the front and back of the car. After a while it becomes obvious when a point is higher or lower than desirable. BTW, there is a section of the parts catalog with reference dimensions. We checked most of those and were surprised how close we got.

Our biggest challenge was the garage floor which was not so level - so we did need to do a bit of fudging!

Good luck!
 
Keith....can it really be true???

Is that a Mimosa TR3 in the making, that I see in these pictures??
 
Laser level I never thought of that, thanks. I know it's going to be a lot of trial and error, that's why I'm doing it this way before paint. I think I will get all the mounting bolts started then start hanging the panels from back to the front, and then tighten everything down and see what starts to shift.

The engine and trans will have to be installed to get even furture needed adjustments as the frame settles with the weigth on the tires. This is where the head banging starts to come into play, work and rework and try again.

The area I wanted to place the rubber between the outer rails and the floor is in between the the square mounting pads.

The color is only primer, will be painted Winchester blue in the end.
 
Sorry Paul but no, it does look great on your car though.
 
:lol:

An anecdotal tale:

When I first tore down the Elan to repair some frame damage, to be dead-sure the thing was level we drilled into the concrete floor, planted threaded anchors into it at various points and used 5/8" all-thread and steel (3/8" IIRC) plates to true up a "platform" to hold the frame. Plumb bob and "chalk lines" on the floor for checking geometry. It may not work as well for panel fitting, as the chassis flex once the car is on its feet may shift alignment. But a thing to keep in mind for chassis checking/tweaking on an irregular floor.
