While I was having some 2 chamber flows put on the merc, sounds bad ass btw, I snapped a few pics of the rear end. any idea if this looks like a gm 10 bolt from like a 77-85 caprice? i'd like to source a rear swaybar for the car. The frame under the car is supposedly a 77-85 caprice frame we thought a parissiene but it has the stock motor mounts for a sbc.

Looks like a B-O-P 10 bolt...not the same as the Chevy 10 bolt. The "moon" cutouts on the cover are the giveaway.

So far as the mounts go, GM started using the "corporate" SBC in '77 if I recall correctly.

Hmm when I bought it I was told it was maybe the frame from a late 70's pontiac parisienne.

B.O.P. 8.2-inch 10-boltThis axle would probably only turn up in a '67-'69 Firebird, but after all these years, who knows what swapping has gone on before you got there. It still has ten bolts in the cover, but note the two cutouts in the nine and three o'clock positions. The B.O.P. rear also uses flanged axle retention, rather than the C-clips used on the other two assemblies. View Related Article

Yeah...they are in a lot more than Firebirds, though. Probably in Olds intermediates more than anything else, but I've also seen 'em in LeMans, Skylarks, etc. Randy's still carries some parts for them. Looks like Hotchkiss may make a swaybar that will work, 2205R.

I swapped in a 75 el camino frame in a 50 mercury ..handles like a super speedway car , same frame

Homespun, when I look at that link the mounting holes look different?

That is the same as what he said, BOP is Buick, Olds, Pontiac. I Cannot confirm what it came out of though. The tag should mean it is a posi on one of the 10 bolts. Dave

Might be. It's listed for late '70s Buick/Olds/Pontiac/Chevy big cars...Caprices, Bonnevilles, & so forth. I'm not sure that's what you have for a frame, though- those axles are usually found on intermediate frames rather than full-size cars.

 

[Pro Stock John]

Thanks again for the help guys.

When you say intermediate, you are referring to Lemans, Malibu like that? I might have one of those frames, as there is an added section to the frame in the back of the car. Car overall is like 115 inches, but there is a foot section added in the back.

If I could find sway bars this car would handle awesome.

maybe a g body frame?...

whats the wheel base.

upper control arms?...

if it was 67-69 f body it would have leaf spring perches instead of lower control arm, and coil spring mounts.

 

[lsone_chevelle]

dont hold me to this but the BOP and Chev 10 bolts had a couple versions. Some having little square notches on the bottom of the housing(like yours) and ones that have half moon indentations where the square notches are found. Yours is the more desirable of the 2.

 

[lsone_chevelle]

shocks are on the wrong side for a 68-72 A body.

 

[ten5nova]

Don't some BOP rears have bolt in axles? If so, might be something to look for.

 

[Dr. Evil]

I'm gonna say 73-77 GM A-body.

Thats what the rear suspension looks like to me and a BOP car from that era would have that axle in it.

77 up Full size GM would have an 7.5 or 8.5

G-body won't have that axle and lower shock mounts.

Yup, 8.2 10 bolt. I had one in a 1970 Camaro and found out the hard way when I went to get bearings for it! The parts DO NOT interchange with the more common 8.5 10 bolt like my 1972 & 1973 Camaros came with.

Some of the Pariseine how ever you spell it came with a sbc from the factory.......a friend of mine parents had one in the 80's......

whats the wheel base.

upper control arms?...

Yup...mid-size cars. Is the wheelbase 115", or the overall length of the car? Edit...118"? Hmm...not a '77 wagon, either...makes me think the frame is older than '77.

A Caprice or Parisienne of the generation starting in '77 had 116" WB, actually the same as a 4-door Chevelle of that year. Was the extra frame rail added behind the rear axle?

I had the same experience with my 72 Chevelle, bought parts thinking it was an 8.5 ten bolt, found out quickly that it was an 8.2.
