My TR3 is currently my only functional vehicle and I need to replace the 
rear gearbox mount. Since the nearest hardware store is about 10 miles 
away I would like the swap to go quickly & smooth (yah right). I have a 
new mount & nuts that attach to the back of the gearbox. I would like to 
replace the bolts that connects the mount to the plate on the frame and 
possibly the bolts that connect the frame plate to the frame.

Could someone please let me know what size bolts are need to fit the 
gearbox mount to the steel frame bracket? And the size bolt  that 
connects the steel frame bracket to the frame? Since the TR is my only 
transportation I would like to quickly get in get the replacement done & 
get back on the road (as if any project goes as planned).

By the way, the U-joint part numbers I asked about earlier received a 
few replies all of which were obsolete numbers. Thank you to the people 
who took the time to reply and I suggest that you update your part 
numbers lists.

My TR's 20+ year old U-joints were badly worn but I discovered a broken 
rear gearbox mount. Hopefully to be sorted out soon.

My area's rainy season is due in the next month or so. It is getting to 
be time to remove the factory style luggage rack, polish it and place it 
into dry storage then get out the side curtains.
