Hello,

That bend is in his 1968 upper steering column half which is there to accomodate funky breakaway busings the federally mandated collapsing scolumn.

Progress report on modifing a 140 brake booster stand to fit in place of a 122 brake master with a manual transmission.

I removed the body side mounting flange from the donor early 140 brake booster bracket by carefully cutting just above the weld at the end of the tube till I just broke through flange and then removed it by twisting it off, leaving a very small piece of the flange and the weld still on the tube and then I ground the weld off the tube at my grinding wheel. This took less than half an hour

I have made a cardboard template for the flange using the 1969-1970 122S brake booster as a guide but with the hole pattern that will allow the modified booster stand to bolt to the 2 existing master cylinder mounting nuts that are welded to the pedal box. I made my template with a third hole to more closely copy the original 1969-1970 122S brake booster stand, although I have seen the brake booster stand that 66-estate is using and it only has 2 holes. I have been working on Volvos since 1978, and I have never seen that brake booster stand and I suspect it has also been modified as it is turning out to be pretty easy modifaction.

I have copied the template onto a 1/4" piece of steel plate which is the same thickness as the original 1969-1970 brake booster stand flange and drilled the large center hole and the 3 mounting holes and I checked the work by bolting a brake master cylinder to the plate. I plan on having my neighbor with a mill cut the flange out of the plate and if he had not left early today, I would have been able to finish the modification to the brake booster stand and it would have been ready for paint.

I guestimate that with a premade template and access to a mill that the brake booster modifiction would take less than 2 hours to perform.
