Setting EM / FC rear Wheel "TOE"
Posted by: 2ragtops ()

I have removed many P/G's from late cars, but never from an early.

I dropped this power pack for a club member, and it has a box of two bolt shims [read 8 of them] on the back of the transmission [P/G] to shim it out to meet the cross member.

Is this right? Can't find anything in the shop manual about it.

Hopefully you kept them together as removed... those are alignment shims for rear wheel TOE adjustment.

1961 Shop Manual

Page 3-5 for rear alignment instructions

Page 3-18 for installing rear transmission crossmember

Figure 3-35 shows shims for both referenced pages.

That toe adjustment is an approximation, since the engine is cradled in rubber mounts. In order to get it correct, you have to do some pushing and prodding to get the engine and transaxle to get it set correctly. That means that you have to loosen the engine and transmission mounts and fuss with it till it settles in with the correct toe adjustment. As my alignment man said, " there aren't enough hours in a day to try to get it exact. When you tighten everything up, and then check the readings, they have changed again. I often wonder how it was done at the manufacturing plant. On my 64 Spyder, it took 3 "adjustments" before it stayed where it belonged. If any of your mounts are failing, it is fruitless to attempt an alignment until you replace the worn and defective parts.

A part of the Rear alignment was to loosen the castellated nut on the rear mount so the powertrain could be moved back and forth without a stress/preload on the rear mount. Since that involved removal of rear exh grill and mount cover and the seal strip across the rear THEN replacing after alignment was finished those steps were forgotten by many. Needless to say the rear alignment was not satisfactory.

As Junk said.. the transmission mounts must be firm in order to set Toe. If the mounts move around because they are warn, lose or in anyway sagging, it will be quite impossible to accurately set toe.

Also any change you make in rear camber, either in rear coil springs or leaf spring​ shims on a 64, will effect toe-in.

Any idea how much the toe will change per inch of ride height?
Anyway, that means you should recheck/adjust toe after changing ride height much?

You can set it fine with somewhat bad mounts. You just have to only loosen the engine mount and put tension on it to set the toe. You might have to take some shims out to get enough tension. The tension will take up the slip in bad mounts. If it was a manual solid mounts would be the right way to do it. I make solid transmission mounts with studs so they are adjustable for camber also.
DO NOT use solid mounts on an automatic. The aluminum ears aren't strong enough.

Mine is a manual, but this may help.

Think I still have the book and "tool" if you want to borrow them.
