'70 engine/tranny mounting hardware

[zymurgist]

I have a '70 911 with a 915 transmission. I dropped the engine to replace the shift rod and I want to make sure I'm using the right parts to put it back together.

1. The transmission mouting bolt part number is 901.305.317.00, correct?

2. How about the curved washers? My tranny was mouted with only one of them. Anybody know the part number for them?

3. Engine mounting bolts... these appear to be straightforward. There are large washers on the top of the engine mounts... what about between the engine mounts (on body) and the engine mounting bar? Are there supposed to be large curved washers there as well? Part number?

Thanks for any help.

Ken,

The engine mount bolts are M12 x 1.5 x 92 (900.082.026.01)
picture linked below with the flat end.

The transmission mount bolts are a special bolt with a tapered
starting point (901.305.317.00). The one pictured below seems
longer than I remember, as if it were for a late 912 ('69?).

The large dished washers (901.305.311.00) curve away from the rubber mounts. There is one of these large washers on either side of the rubber mounts, both engine and transmission for a total of six per 911. The upper curved washer for the transmission mount is integrated in the torsion bar tube assembly.

Here is the prior thread “Bolt sizes”

Best,
Grady

Thanks, Grady.

I had seen the previous thread, but I couldn't find the part numbers for the washers. I'll be putting together an order for PP as soon as I figure out everthing I need for the 911 and the 914.

(And of course, as soon as the order gets here, I'll think of a $2.00 part that I forgot.)
