K-5 frames

[Stonewall2]

I have been told there are substantial differences made over the years on K-5 frames? Also that the K-5 frames were the same as light pick up frames for any given year?

I had always thought there were insignificant changes made to frames during the K-5's production years.

Does any one have input on the K-5 frames as to changes?

OK, tracked down the skinny on K-5 frames. So if anyone else may be interested in towing their K-5 this is the info I found.

The only manufacturer of the frame base plate I found was:

Blue Ox Products
PO Box P | One Mill Road, Industrial Park
Pender, NE 68047
888-425-5382 | 402-385-3360 (Fax)

They make it for: 80-87 Blazer (full size) P/N#-DM7516 Price of base plate, adaptor & shipping to AZ was $198.00

I have a Excali-Bar tow bar and it required The $48.00 Duncan adaptor .

No Jimmy is listed, but the frames are the same for those years

After action report for flat towing of the 85 K-5 Jimmy.

Towed the Jimmy (4 spd. 700 R-4 auto tranny) up to Arizona high country. Front manual hubs locked out, 700 R-4 tranny in neutral, 208 NP manual transfer case in neutral, key in first notch to allow steering wheel freedom of movement.

towed for ten miles and checked, all appeared OK, checked again at 100 miles and found transfer case very warm & vent line was burping small amount of fluid. Checked again at 150 miles and found the transfer case hotter than hell (sizzled saliva when spat upon, also by this time it was really blowing tranny fluid (what it uses) out the transfer case vent line.

I proceeded to drop the rear drive line, continued trip with no other problems. reinstalled rear drive line on arrival and all seemed fine, drove a couple hundred miles HWY and (very) rough back roads & 4x4 trails with no adverse effects noticed.

Dropped rear drive line and trip back home was uneventful as to towing. Now using Jimmy for local driving and have noticed no problems, so apparently no permanent damage occurred.

Have no idea as to problem unless the transfer case components do not take well to becoming driven, instead of drivers. The 208 NP transfer case does have an oil pump, so maybe it did not perform as intended. The thing is, there is no normal driving cooling of transfer case fluid, so what really gives, have no real idea?

One thing I did noticed that seemed odd, with the transfer case in neutral, no input is induced into the R-4 tranny,(it stayed cool as the proverbial cucumber) but the front drive shaft rotated (locked in solid with rear) when Jimmy was under tow and rear drive line was bolted up.

Any constructive input would be appreciated for enlightenment.
