Default Need Benwil mounting plate dimensions

I know this is an old thread but I was hoping someone would be willing to give me some measurements on a benwil tp9 or tp7 baseplate. it is the 2post with the drive over plate. I recentlly got one without a mounting plate and need to build one but don't have the dimensions.
I have a parts diagram but it does not have the measurements. I did see in one of the pictures that it is 144.5 inches wide but that looks like it is with the mounting tabs and I have no idea what size the mounting tabs are it makes it hard to guess the width, I am assuming that I will need to be fairly accurate with the width since the chain that goes from side to side is a specific length.
I am in NH so if anyone has one in a reasonable driving distance I would love to come and get some measurements myself. I would be willing to drive to Massachusets, New Hampshire, Maine, or even Rhode Island, Vermont or Connecticut.
What I need most is:
(1) what size is the square steel for the mounting plate. looks like 2x2 inches in pictures but pictures can be deceiving.
(2) what is the width of the Mounting plate not including the mounting pads for the bolts.That should get me the right width for the pasts.
(3) what is the length of the square steel that runs up the sides of the mounting plate (the part that bolts to the floor) looks like about 3 feet long but again pictures can be deceiving.
Thanks for any possible!

Can't help anybody with the information but just wanted to say congratulations to all the people whom have lifts..

I love mine and it gets used at least 3 days a week.. Sometimes more and the nice thing is it's usually paying jobs so adds some funds for shop stuff..

If I defend myself I am attacked.

My meaningless thoughts are showing me a meaningless world.

My attack thoughts are attacking my invulnerability.

I'd like to think of something smart, but I don't want to hurt myself.

I passed on a lift about 6 years ago, and have been kicking myself ever since, and looking for another.

One of the reasons I passed on the lift was my concrete is of unknown quality/thickness - but an engineer buddy of mine said just mount the lift to a plate about 18" square, then mount the plate to the floor. (1/2 to 3/4" thickness) He said that would spread the load enough for sub par concrete.

Congrats on the lift, and the shop, of course. I am envious!

Sun Seeker, you might try SVI Inc.

Their page states "SVI has the repair parts you need for Benwil! If it’s not in stock, SVI will make it using original Benwil engineering drawings."

If they have the original engineering drawings, they may provide you with the measurements if you ask nicely; worst case you may be able to purchase a manual from them.

You could also try contacting THIS GUY. The email address is from 2009, but worth a shot.
There is nothing quite as permanent as a good temporary repair.
