Frame alignment

I've asked the body shop to make sure the frame on my 64BJ8 is straight. He says because the car is old, he doesn't know what the spec numbers are. Can I provide them for him.

Can anyone help me? Or tell me where I can find what ever numbers he needs.

Thank you, Roger
 
The Austin Healey 100 and 3000 workshop manual shows the chasis frame in Section R, inside frame width front, 17 in.; outside frame width front, 23 in.; outside of rear spring brackets, 40 11/16 in.; and inside rear, 17 in. according to my manual, but it only includes through early 3000's. Also pg 197 of the Haynes 100/6 & 3000 workshop manual shows a chasis alignment diagram through the BJ7. If you want I can fax a copy of it to you. Pg 199 of the Haynes also shows the same diagram as the Healey Manual.

I had a pretty good look at your frame when I was under there a while back. Unfortunately, I do know what a molested BJ8 frame looks like. And your frame "looks" very straight and unmolested to me - well, except for that little dimple that Pepe gave you.

Have you any reason to believe that your frame is anything other than correct? You know, shipwright's disease can take your breath away (and bank account) with these cars if you let it.

Hi Randy, happy holidays. Thanks for looking into my posts, and taking the time. Reason for wanting to check the frame, is because after getting the car bead blasted, that showed all the damaged and repairs made by PO. Which as you know, was not repaired with quality in mind. So the question arises, was there frame damage, and did the PO's body shop check the frame for alignment? If so, how good of an alignment did they do? They didn't do a very good job on body repair.

This is the time to address the question, while I am haveing all this body work done. I am having the shop pay close attention to all the gaps. Best to make sure the frame is correct first. I don't want to spend all the time and money on lineing up body panels, to find that the frame needed to be tweeked. Which may affect body panel gaps, and tire wear. Best to be safe than sorry. Cheers, roger
 
Roger,

Using the factory numbers for frame alignment is good but probably more important is that the frame is aligned in the x,y and z plane i.e. that both sides are the same. On a frame machine you can check one side against the other to make sure it is within tolerance and that will tell you if it has been in an accident or tweaked otherwise (P.O's trying to re-enact the driving scene from Bullet!)

Cheers,
John
