hello, im fairly new to the board but all ive ever owned are volvos. not that ive been driving very long (6 years), but still. i currently have an 84 245 and am looking to buy a 74 164e. the thing is, the brake booster on the 164 is caput. the owner said her mechanic told her a booster from a 240 could fit the 164's MC with some mods. any ideas on how to make this work? also, anyone know about other parts compatability between the 240, 140, and 164? it would be nice to use some of those good parts off my 84 (like nice new calipers) and it would make shopping a little easier. any and all advice/help/counsel would be appreciated.

If you get stuck, get parts from www.scandcar.com in the Netherlands. It is mostly OEM and I have not had any problems ordering from them half way around the globe from New Zealand. They also have a workshop with lots of technical knowledge. International delivery takes about 10 work days to your door.

From 73- on, the seats and interiors interchange. On a 75, virtually everything behind the windshield is identical to the 240, introduced that year.

I don't believe any of the front brake hardware is the same, but the rears are interchangeable with 240 all the way to the end of production.

Hi. Having owned a '73 164 and currently a '75, along with a string of 240's, I can't agree 100% about the interior. The '75 164 is the only one that's fully interchangeable (viz. the interior) with the 240's; while the '74 and earlier were more like the 140's (that isn't to say, however, that certain 240's parts won't fit anyway -- it's on a item by item basis -- some will, some won't).
However, about your '74's brakes:
The front rotors are distinct, strictly a '72-75 164 item, not the same as the 140's, or the 240's, parts. Likewise, the front calipers are a unique '72-75 164 item (no match to 140's or 240's).
The 164 rear rotors for only the '75 interchange with all the 240's for years on -- whereas your '74 164 rear rotor matches to all 140's and 164's that are '67 to '74, but not to the '75 164. And your '74 ATE rear calipers (they were Girling only '69-71) match with 164's from '72-74 ('75's is different), and 140's from '70-74.
Here's the breakdown of p/n's for your '74 164 (from Volvos' Quick Reference Parts Catalog, dated April 1990):
front rotors: 270735-4
rear rotors: 270731-3
front calipers: 5002018-9 (L), 5002019-7 (R)
rear calipers: 5002002-3 (L), 5002003-1 (R)

Hope this helps.

thanks very much for the pointers. that's very good to know about the brakes, knowing the part #s is very helpful. im going to look at the car in sunday, so if i get ill know where to come to for advice! thanks again
ps - if anyone has a spare brake booster for a '74 164, let me know!
