Safest way?

[SLR_dave]

Interesting problem, I have do do a chassis change at some point - and swap all the running gear, I hadn't considered that issue....

I think, now considering this thread, when I get around to it I'll do it by putting the body and engine on the new chassis first before swapping the springs, that would be a safer way I think.

Maybe you could temporarily bolt the engine and gearbox back in? That would give you some weight..., might not be enough though, I dunno.

I'd be using a good internal spring compressor too, the external ones can sometimes be made to work on H series, but it's not right, I did it last time with an internal kingchrome one, even then, it only just cleared (with a nudge- grimace! ) and I had to use extra spacers on the compressor.

Sure Ive been told some people just jack em in, no compressor at all, but that always seemed pretty dodge to me from a 'not getting a spring in the head' point of veiw, and also I dunno if they always end up sitting straight done like that, - you also want to make sure the bottom end of the coil sits so it doesnt block the water drain hole in the lower arm.

But I wonder if Holden still sell the original tool - Gregorys manual list it as " Compression tool set number 3A15" and (if you can find one) to Ensure the tool plate is inserted between the bottom 3rd and 4th coils with the offset hole toward the engine " Might be worth a look around, just maybe they are even in stock..., somewhere, I've never seen one, but maybe if you can get exactly the right spring compressor tool, using shorter springs, you might not need to jack the lower wishbone up at all. Probably "safest"?
