Remember a reference to some type of alignment bolts used in installling a 4 speed transmission to bellhousing. Have 77 L-82 with M-21. Does anyone know of these bolts, what they are called and where to get them. Thanks.

Re: Transmission Installation Bolts
George-----
This is an easy one. Transmission alignment bolts are nothing more than a "stud" or "headless bolt" used to make installation of the transmission to the bellhousing easier. To obatin them, go tou your local hardware store and purchase four 1/2-13 bolts of about 6" to 8" length. Cut of the heads with a hacksaw or similar tool and bevel the edges of the cut-off end on a grinder. That's all there is to it. Install these bolts in place of the transmission mount bolts and use them to guide the transmission into its residence on the bellhousing. After the transmission is FULLY SEATED, remove the bolts one at a time and replace with the normal transmission bolts. DO NOT ATTEMPT TO SEAT A NON-FULLY SEATED TRANSMISSION BY "DRAWING IT DOWN" WITH THE TRANSMISSION MOUNT BOLTS. This is how ears are snapped off of transmission main cases. The transmission MUST be FULLY SEATED prior to the installation of the transmission-to-bellhousing bolts.
One tip on the alignment bolts: buy the lowest grade(NO lines on head)you can find. For alignment bolts, strength is NOT required and you want them to be as easy to cut the heads off of as possible(i.e. hardened bolts are much harder to cut).In Appreciation of John Hinckley -
Re: Transmission Installation Bolts
Joe's advice is correct. The only thing I can add is to cut a screw driver slot into the beveled end of the guide to help with the removal.Comment

How heavy is transmission?
I'm faced with putting in a clutch on a 69 427/390. Can I handle the transmission by myself or do I need transmission jack or something?Comment

Re: How heavy is transmission?
I "estimate" a Municie is about 60-70lbs. Taking it out is the easy part, Getting it back in... Well that's not so easy. But I did it myself last summer, and I'm no Mr. Atlas. I did use Joe's tip about the guide bolts though, it really helps.Comment

Re: How heavy is transmission?
Bob, I removed/installed the Muncie in my '69 427/400 last year by myself, without a transmission jack. Get the car up fairly high in the air(and supported securely on solid jackstands) and use a good floor jack to get the tranny back close to its original position. It would be really helpful to have a second person to run the floor jack up while you're under the car guiding the tranny, but its not critical. (I was just too darn proud to ask the spouse for assistance at this point!)
Even if you do everything properly, you'll still have a reasonable chance of getting "up close and personal" with that tranny before its back in place. A set of mechanics gloves and safety glasses would be recommended, as it helps to even up the ensuing wrestling match!
Good luck,
EdComment

Start working on those triceps
For those of us who find it a challenge to fit under the car even after it is jacked up, I suggest working on those triceps. Lay on your back with your arms extended above your head. Grab one of your smaller children or grandchildren as the case may be and press them up over your head while attempting to crawl and wriggle your body under the now suspended child. Now hold them up there for 15 minutes or so thrashing them about. This is to simulate the many unsuccessful attempts you may encounter on getting the input shaft stabbed in correctly. No need to practice the cuss words at this point since the child is present. Trust me, you will not be at a loss for words. You can quit when your arms ache, placing the child on your chest, because that is where the tranny is likely to spend some time. Then again, you might get lucky the first time or use some of the pointers others have suggested.Comment

Re: Transmission Installation Bolts
If the bolt routine is a bother, Mr Gasket sells these bolts with the slots cut in the end. I think they are about 4 inches long and cheap.Comment
